Abstract
Description
Alkylarylsulfonates alcalins utilisables pour l'élimination des résidus d'insecticides sur les fruits et légumes
Par suite de l'expansion actuelle de l'agriculture, on peut assurer que tout produit végétal, comme les fruits, les légumes, etc. a préalablement subi une série de traitements préventifs avant qu'il parvienne au consommateur, soit pour des mobiles économiques, spécialement l'amélioration du rendement du sol moyennant des engrais chimiques, par exemple azotés, phosphatés, potassiques, calciques, etc., soit pour des motifs de prévention des maladies des végétaux pouvant rendre inutilisables les produits naturels en vue de la consommation humaine.Alkaline alkylarylsulfonates usable for the removal of insecticide residues on fruits and vegetables
As a result of the current expansion of agriculture, it can be ensured that any plant product, such as fruit, vegetables, etc. has previously undergone a series of preventive treatments before it reaches the consumer, either for economic motives, especially the improvement of the yield of the soil by means of chemical fertilizers, for example nitrogen, phosphates, potassium, calcium, etc., or for reasons for preventing plant diseases which could make natural products unusable for human consumption.
L'emploi d'herbicides, insecticides, fongicides, etc., s'est imposé de façon générale dans l'agriculture moderne. Tous ces pro- duits se basent sur des composants organiques aux groupes fonctionnels parfaitement définis tels que chlore, phosphore, carbamates et méthylcarbamates, thiocyanates, bromures, thiocarbamates, mercaptans, amines et amides, sulfamates, sulfonamides, triazines, etc. The use of herbicides, insecticides, fungicides, etc. has become generally accepted in modern agriculture. All these products are based on organic components with perfectly defined functional groups such as chlorine, phosphorus, carbamates and methylcarbamates, thiocyanates, bromides, thiocarbamates, mercaptans, amines and amides, sulfamates, sulfonamides, triazines, etc.
Au moins 90% de tous ces groupes fonctionnels, se trouvant associés à des composés aliphatiques et/ou aromatiques et aux cyclanes, procurant des produits insolubles dans l'eau, aussi un simple lavage ne fait pas disparaître le résidu qui, généralement, est nuisible à la santé, d'autant plus que, pour intensifier l'effet du produit basique on lui ajoute des composés tensioactifs qui en augmentent l'adhérence au corps du végétal, pour ainsi produire un effet bactéricide ; pour l'application sur les champs on emploie fréquemment d'autres agents mouillants qui augmentent davantage la faible solubilité dans l'eau. At least 90% of all these functional groups, being associated with aliphatic and / or aromatic compounds and with cyclanes, providing products insoluble in water, also a simple washing does not remove the residue which, generally, is harmful to health, especially since, to intensify the effect of the basic product, surface-active compounds are added to it which increase its adhesion to the body of the plant, thereby producing a bactericidal effect; for application in the fields, other wetting agents are frequently used which further increase the low solubility in water.
L'objet de la présente est un produit solubilisateur des résidus et. des principes actifs déposés sur les végétaux permettant d'éliminer d'une façon simple, commode et score, tous les résidus et les principes actifs présents sur les fruits et légumes, en faisant ainsi disparaître tout danger pour la santé. The object of this is a product solubilizer of residues and. active ingredients deposited on plants to eliminate in a simple, convenient and score, all residues and active ingredients present on fruits and vegetables, thereby eliminating any danger to health.
Les fruits et légumes traités avec le produit selon l'invention sont débarrassés de tous les résidus des insecticides, etc., de sorte que la réaction avec la cellulose de la peau des végétaux ne se produit pas, ce qui évite la fermentation et la putréfaction de celle-ci. The fruits and vegetables treated with the product according to the invention are freed from all the residues of insecticides, etc., so that the reaction with the cellulose of the skin of the plants does not take place, which avoids fermentation and putrefaction. of it.
Le produit selon l'invention, pour l'élimination des résidus et des principes actifs sur les plantes, est un alkylaryl sulfone te alcalin de la formule générale
où X est Na, K, etc., et "n" vaut de 10 à 18.The product according to the invention, for the elimination of residues and active principles on plants, is an alkaline alkylaryl sulfone te of the general formula
where X is Na, K, etc., and "n" is 10 to 18.
L'hydrocarbure aliphatique employé comme substance de départ provient d'un dérivé du pétrole correspondant. The aliphatic hydrocarbon used as starting material comes from a corresponding petroleum derivative.
Le procédé pour l'obtention du produit selon l'invention comprend les étapes suivantes :
a) chloration d'un hydrocarbure de la formule générale
C H pour y obtenir un dérivé aliphatique monochloré de formule
n 2n+2
C H Cl qui
n 2n+l
b) est condensé avec un hydrocarbure aromatique, tel que le benzène, pour y obtenir unalkylaryle de formule générale
lequel
c) est soumis à sulfonation pour y obtenir un acide alkylarylsulfonique de
qui postérieurement est purifié et ensuite neutralisé avec un carbonate alcalin.The process for obtaining the product according to the invention comprises the following stages:
a) chlorination of a hydrocarbon of the general formula
CH to obtain a monochlorinated aliphatic derivative of formula
n 2n + 2
CH Cl who
n 2n + l
b) is condensed with an aromatic hydrocarbon, such as benzene, to obtain an alkylaryl of general formula
which
c) is subjected to sulfonation in order to obtain therein an alkylarylsulfonic acid of
which is subsequently purified and then neutralized with an alkaline carbonate.
I1 est important que pendant la première étape du procédé la formation de produits chlorés d'ordre supérieur (dichlores, trichlores, etc.) soit empêchée. It is important that during the first step of the process the formation of higher-order chlorinated products (dichlorides, trichlorides, etc.) is prevented.
On a essayé de remplacer le chlore par le brome, mais malgré la qualité du produit final l'emploi de bromures a été rejeté par deux motifs évidents : leur coat et le risque de toxicité. We tried to replace chlorine with bromine, but despite the quality of the final product the use of bromides was rejected by two obvious reasons: their coat and the risk of toxicity.
