  "Procédé de préparation d'agents d'usinage, de nettoyage et de pro- tection anticorrosive de métaux, solubles dans l'eau et exempts d'huiles minérales" 
La présente invention a pour objet un procédé de prépara- tion d'agents exempts d'huiles minérales pour l'usinage, le nettoya- ge et la protection anticorrosive de métaux, procédé qui consiste à sulfochlorer des hydrocarbures saturés aliphatiques ou cycloalipha- tiques, à faire réagir les sulfochlorures avec de l'ammoniaque ou

 <Desc/Clms Page number 2> 

 ci et à libérer les mélanges obtenus de tout hydrocarbure inchangé, 
On   connat   des produits auxiliaires d'usinage des métaux à base d'huiles minérales contenant des acides   ailles   sulfonamido- carboxyliques sous forme de leurs sels avec des mentaux alcalins ou alcaline-terreux ou avec des bases d'azote organiques.

   Les acides alkyles   sulfonamido-carboxyliques   qui y sont contenus correspondent à la formule générale : 
R - X- (R1COOH)n 
Dans cette formule, R et R1 désignent des restes   d'hydro-   carbures saturés aliphatiques ou cycloaliphatiques, identiques ou différents, dont au moins un, de préférence R, contient au moins 6, de préférence 10 à 20 atomes de carbone, X désigne le groupement 
 EMI2.1 
 et n désigne 1 ou 2. 



   Techniquement, detels composés sont obtenus au départ   par exemple des coupes de pétrole parafféniques d'hydrocarbures aliphatiques. Il est souhaitable d'obtenir un nombre   de   composés   aussi élevé que possible dérivant des acides alkyles monosalfoniques, C'est pourquoi on interrompt la sulfochloration dès que la moitié à peu près des hydrocarbures utilisés a réagi. Ainsi, on obtient toujours des mélanges réactionnels consistant à peu près pour la moitié en acide alkyle sulfonamido-carboxylique et pour la moitié en huile minérale. Après la neutralisation des acides, les mélanges peuvent être mélangés avec de l'eau et utilisés comme auxiliaires d'usinage de métaux. 



   A présent, il faut que ces produits connus soient débar- rassés des huiles avant qu'ils arrivent, après usage, dans les eaux industrielles. Il est cependant possible de séparer l'huile minérale des mélanges obtenus lors de la préparation et consistant en sels des acides alkyles sulfonamido-carboxyliques et d'huile minérale en faisant réagir ces mélanges avec de l'acétone aqueuse à 85% par exemple. L'huile minérale se sépare alors comme phase plus légère. 



  Elle peut être extraite et réintroduite dans la sulfochloration. 



  Néanmoins, il faut récupérer l'acétone du produit déshuilé par distillation, ce qui représente un enchérissement considérable 

 <Desc/Clms Page number 3> 

 du procédé. 



   Or, la demanderesse a trouvé un procédé de préparation de produits d'usinage, de nettoyage et de protection anticorrosive de métaux, solubles dans l'eau et exempts d'huiles minérales, procédé qui consiste à sulfochlorer des hydrocarbures saturés aliphatiques ou cycloaliphatiques contenant au moins 6 et de préférence 10 à 20 atomes de carbone, à faire réagir les sulfochlorures avec de l'ammoniaque ou des amines primaires et les sulfonamides   alkyliques   obtenues en présence d'alcali avec des acides   halogènes   carboxyli- ques et à neutraliser les acides alkyles sulfonamido-carboxyliques obtenus.

   Le procédé de la présente invention est caractérisé par le fait que la neutralisation est effectuée avec une quantité d'une base d'azote organique telle que chaque atome d'azote contenu dans   @   la molécule de base comporte au moins 3 moles d'oxyde d'éthylène, que la solution aqueuse du sel formé ait; un pH d'environ 8 à 8,5. 



   Dans le cas le plus simple la neutralisation peut se faire      avec de la triéthanolamine. Il convient pourtant mieux d'utiliser des alcanolamines plus fortement éthoxylées étant donné que les produits obtenus à partir de ces composés ont des propriétés de solubilité meilleures. Conviennent très bien par exemple les tri- éthanolamines éthoxylées ayant un poids moléculaire entre 280 et 750, en plus des produits d'addition d'oxyde d'éthylène aux   diamine.   d'éthylène, triamine diéthylénique, diamine propylénique, amines de propanol ou de butanol, amines alkyles ou aryles pour autant que ces produits d'addition contiennent au moins 3 moles d'oxyde d'éthylène par atome d'azote. 



   Il n'est pas nécessaire d'ajouter au mélange de réaction la base dans la quantité stoechiométrique requise pour la neutra- lisation. Pour obtenir le pH désiré d'environ 8,5, il faut que   1on   utilise, en général, un excès de base. Cet excès peut être ajouté sous forme d'une base d'azote contenant moins de 3 moles d'oxyde d'éthylène par atome d'azote, par exemple la mono- ou diéthanolamine, 

 <Desc/Clms Page number 4> 

 la morpholine ou des bases semblables. En réalisant le procédé de la présente invention dans la pratique il s'est révélé opportun d'ajouter 50 parties en poids de base par 100 parties en poids du mélange réactionnel. 



   La séparation de l'huile minérale peut se faire à la température ambiante, Elle exige pourtant beaucoup moins de temps si le mélange est chauffé, après addition de la base, à environ 
50 à environ   80 C.   



   Les sels d'acides alkyles sulfonamido-carboxyliques exempts d'huile minérale obtenus selon le procédé de la présente invention sont des liquides visqueux miscibles à l'eau dans n'im- porte quelle proportion. Pour l'application comme produits auxiliai- res d'usinage de métaux on peut ajouter aux solutions aqueuses en vue d'augmenter l'activité de protection contre la corrosion des anticorrosifs connus en soi, comme par exemple le sulfonate de pétrole, le sulfonate d'alkylaryle, les sels d'acides naphténiques et d'acides gras, les amines aliphatiques, les alcanolamines d'aci- des gras, les esters alcanolamines d'acides gras, les sels d'amines aliphatiques d'acides organiques, comme par exemple l'acide acétique, l'acide d'huile de coco, l'acide oléique, l'acide gras de tall oil, la sarcosine d'acyle gras, la taurine d'acyle gras, l'acide ben-   zolque,

     etc, en plus les esters d'acide phosphorique organiques et les sels d'esters partiels d'acide phosphorique organiques, les phosphates alcanolamines, les phosphites organiques, le xanthogène diisopropylique, le nitride de sodium ainsi que les nitrites d'au- tres bases minérales ou organiques. En vue d'obtenir des mélanges homogènes des produits préparés selon le procédé de la présente in- vention avec les composantes de combinaison mentionnées ci-dessus, l'emploi additionnel de composéshydrotropes comme agents solubili-' sants peut se révéler nécessaire ou avantageux. 



   Les exemples qui suivent illustrent la présente invention sans aucunement en limiter la portée, 

 <Desc/Clms Page number 5> 

 EXEMPLE 1 
On fait agir sur une fraction d'hydrocarbure saturé ali- phatique ayant des limites   d'ébullition   de   250 C   à 350 C simultané- ment du chlore et de l'anhydride sulfureux en additionnant d'environ 0,1   à     0,2%   d'un peroxyde organique jusqu'à ce que la moitié à peu près des hydrocarbures soit transformée principalement en monosul- fochlorures.

   On traite le mélange réactionnel par da l'ammoniaque de sorte que l'on obtient un mélange consistant pour environ 50% en hydrocarbures, pour environ 35   à :38%   en sulfamides alkyliques et pour environ 12 à 15% en sulfamides   dialkyliques.   On fait réagir ce mélange en présence d'une lessive alcaline avec de l'acide chlo- roacétique, on l'acidifie ensuite avec de l'acide sulfurique, si nécessaire en ajoutant des agents qui éclaircissent la teinte, en- suite on lave avec de l'eau jusqu'à ce qu'il ne contienne plus d'électrolyte et on l'isole, sa teneur en eau restant   d'environ     7%.   



  Le mélange ainsi obtenu composé d'acides alkyles-sulfamido acéti- ques, d'huile inerte et d'eau est un liquide homogène, huileux ayant un indice d'acide d'environ 50. On le désigne par la suite comme produit A. 



  EXEMPLE 2 
On mélange 100 parties en poids du produit A, préparé se- lon la méthode décrite à l'exemple   1,   d'une manière homogène avec 30 parties en poids de   triéthanolamino-polyglycoléther   d'un poids moléculaire de 750 et avec 20 parties en poids de triéthanolamine,      
On chauffe le mélange à 80 C et on   1 abandonna   pendant trois heures à une température entre 80 C et 50 C.

   Il se produit alors la séparation en deux phases liquides que l'on peut séparer aisément par extraction ou écoulement, la phase supérieure étant composée de 45 parties en poids d'hydrocarbures (huile inerte), la phase inférieure étant composée de 105 parties en poids de sels d'amine alkylsulfamido-acétiques pratiquement exempts d'huile iner- te, Ces derniers sont appelés par la suite produit ES 2. 

 <Desc/Clms Page number 6> 

 



   Le produit ES 2 contient environ 7% d'eau et représente un liquide clair huileux qui se dissout facilement dans l'eau ayant, en solution aqueuse de   5%,   un pH de 8 (électrode en verre) et ne produisant pas, en solution aqueuse de 1,5%,dans le test de corro- sion d'après Herbert, des taches de rouille ou autres (Test der Merbert: des copeaux d'acier, grosseur 50, sont mouillés sur une plaque de fonte grise avec la solution à tester puis abandonnés pendant 24 heures à 20 C et sous 65% d'humidité atmosphérique re- lative et ensuite contrôlés). 



   La partie d'hydrocarbure séparée comme huile inerte peut être/rajoutée à la sulfochloration selon la méthode décrite dans l'exemple 1. 



    EXEMPLE 3   
96 parties en poids du produit ES 2, obtenu selon l'exem-   ple   2, sont mélangées d'une manière homogène avec 4 parties en poids de diéthanolamine, un liquide clair huileux résultant ainsi que se dissout dans l'eau pour donner une solution limpide et qui est mis- cible a l'eau dans n'importe quelle proportion. La solution aqueuse   à 5%   du produit a un pH de 8,5 et la solution aqueuse à 1% ne provo- que pas, dans le test de corrosion d'après Herbert, de taches de   rouillât   ou autres. 



  EXEMPLE 4 
100 parties en poids du produit A, obtenu selon l'exemple 1, sont mélangées d'une manière homogène avec 43 parties en poids 
 EMI6.1 
 de triéthanalamine..polygiycoléther d'un poids moléculaire de 280 et avec 7 parties en poids de triéthanolamine.On chauffe le mélange à 80 C, puis on l'abandonne pendant environ 3 heures à des températu- res entre 80 et 50 C, Il se produit alors la séparation en 2 phases liquides que l'on peut séparer facilement par extraction ou écoule- ment, la phase supérieure étant composée de 45 parties en poids d'hydrocarbures (huile inerte) et la phase inférieure étant composée de 105 parties en poids de sels d'amines   alkylsulfamido-acétiques   

 <Desc/Clms Page number 7> 

 pratiquement exempts d'huile inerte. Ces derniers sont appelés par la suite produit ES 4. 



   Le produit ES 4 contient environ 7% d'eau et représente un liquide clair huileux, facilement soluble dans l'eau ayant, en solution aqueuse de 5%, un pH de 8, et ne provoquant pas en solu- tion aqueuse de 1,5% dans le test de corrosion d'après Herbert de taches dé rouille ou autres.

  "Process for the preparation of agents for machining, cleaning and anticorrosive protection of metals, soluble in water and free from mineral oils"
The present invention relates to a process for preparing agents free from mineral oils for machining, cleaning and anticorrosive protection of metals, a process which consists in sulfochlorinating saturated aliphatic or cycloaliphatic hydrocarbons, reacting the sulfochlorides with ammonia or
 EMI1.1
 amines to form alkyl sulfonamides and alkyl sulfonamides with these halogen carboxylic acids to form
 EMI1.2
 alkyl sulfonamido-ca acids:

  .- ,. ioxylia-Uco, 4 neutralize those-

 <Desc / Clms Page number 2>

 ci and freeing the mixtures obtained from any unchanged hydrocarbon,
Mineral oil-based metalworking aids are known which contain sulphonamido-carboxylic acidic acids in the form of their salts with alkali or alkaline-earth metals or with organic nitrogen bases.

   The alkyl sulfonamido-carboxylic acids contained therein correspond to the general formula:
R - X- (R1COOH) n
In this formula, R and R1 denote aliphatic or cycloaliphatic saturated hydrocarbon residues, identical or different, of which at least one, preferably R, contains at least 6, preferably 10 to 20 carbon atoms, X denotes the group
 EMI2.1
 and n denotes 1 or 2.



   Technically, such compounds are obtained initially, for example, from paraffenic petroleum cuts of aliphatic hydrocarbons. It is desirable to obtain as high a number of compounds as possible deriving from alkyl monosalfonic acids. This is why the sulfochlorination is interrupted as soon as approximately half of the hydrocarbons used have reacted. Thus, one always obtains reaction mixtures consisting approximately half of alkyl sulfonamido-carboxylic acid and half of mineral oil. After neutralization of the acids, the mixtures can be mixed with water and used as metalworking aids.



   Now, these known products must be freed from oils before they arrive, after use, in industrial waters. It is however possible to separate the mineral oil from the mixtures obtained during the preparation and consisting of salts of alkyl sulfonamido-carboxylic acids and mineral oil by reacting these mixtures with 85% aqueous acetone, for example. The mineral oil then separates out as a lighter phase.



  It can be extracted and reintroduced in the sulfochlorination.



  Nevertheless, the acetone must be recovered from the deoiled product by distillation, which represents a considerable cost

 <Desc / Clms Page number 3>

 of the process.



   However, the Applicant has found a process for preparing products for machining, cleaning and anticorrosive protection of metals, soluble in water and free from mineral oils, which process consists in sulfochlorinating saturated aliphatic or cycloaliphatic hydrocarbons containing at least less 6 and preferably 10 to 20 carbon atoms, in reacting the sulfochlorides with ammonia or primary amines and the alkyl sulfonamides obtained in the presence of alkali with halogen carboxylic acids and in neutralizing the alkyl sulfonamido acids -carboxylics obtained.

   The process of the present invention is characterized in that the neutralization is carried out with an amount of an organic nitrogen base such that each nitrogen atom contained in the base molecule contains at least 3 moles of oxide d. ethylene, that the aqueous solution of the salt formed has; a pH of about 8 to 8.5.



   In the simplest case, neutralization can be done with triethanolamine. However, it is better to use alkanolamines which are more strongly ethoxylated since the products obtained from these compounds have better solubility properties. Ethoxylated triethanolamines having a molecular weight between 280 and 750 are very suitable, for example, in addition to the adducts of ethylene oxide to the diamines. ethylene, diethylenic triamine, propylene diamine, propanol or butanol amines, alkyl or aryl amines provided that these adducts contain at least 3 moles of ethylene oxide per nitrogen atom.



   It is not necessary to add the base in the stoichiometric amount required for neutralization to the reaction mixture. To achieve the desired pH of about 8.5, an excess of base should generally be used. This excess can be added in the form of a nitrogen base containing less than 3 moles of ethylene oxide per nitrogen atom, for example mono- or diethanolamine,

 <Desc / Clms Page number 4>

 morpholine or similar bases. In carrying out the process of the present invention in practice it has been found expedient to add 50 parts by weight of base per 100 parts by weight of the reaction mixture.



   The separation of mineral oil can be done at room temperature, but it requires much less time if the mixture is heated, after addition of the base, to approximately
50 to about 80 C.



   The salts of mineral oil-free alkyl sulfonamido-carboxylic acids obtained by the process of the present invention are viscous liquids miscible with water in any proportion. For the application as aids for metalworking, it is possible to add to the aqueous solutions in order to increase the corrosion protection activity anticorrosives known per se, such as for example petroleum sulphonate, dulphonate. 'alkylaryl, salts of naphthenic acids and fatty acids, aliphatic amines, alkanolamines of fatty acids, alkanolamine esters of fatty acids, salts of aliphatic amines of organic acids, such as for example acetic acid, coconut oil acid, oleic acid, tall oil fatty acid, fatty acyl sarcosine, fatty acyl taurine, benzolic acid,

     etc., in addition to organic phosphoric acid esters and salts of organic phosphoric acid partial esters, alkanolamine phosphates, organic phosphites, diisopropyl xanthogen, sodium nitride as well as nitrites of other bases mineral or organic. In order to obtain homogeneous mixtures of the products prepared according to the process of the present invention with the combination components mentioned above, the additional use of hydrotropic compounds as solubilizing agents may prove to be necessary or advantageous.



   The examples which follow illustrate the present invention without in any way limiting its scope,
