PATENT OFFICE SULPHATED CONDENSATION PRODUCTS OF l lill'a.l".l.Y ACIDS AND MONOETHANOLAM- John W. Orelup, Summit, N. J.
No Drawing.
15 Claims;
My present invention relates to improvements in wetting, dispersing and emulsifying agents and more particularly to the sulphonated condensation products of certain fatty acids and the mono- 5 alkyl amines, as for example monoethanol amines. While it has been proposed to condense certain of the fatty acids or esters thereof with various amines, the proper acids or mixtures thereof have not been condensed with a proper amine. In
many cases the condensation products so obtained have not been treated with sulphuric acid to form compounds therewith. In all casesthe proposed products have been practically worthless. The following table gives results obtained by observing the sinking time of a piece of wool serge 4 x 4 in a solution of one gram of the wetting agent per litre of tap water of average hardness. The wetting agents were all made by condensing the acid mixture indicated with monoethanolamine followed by treatment with sulphuric acid as described in detail below.
' Sinking time at 26 C.
Sulphuric acid treated condensation product formed from:
First fraction composed of 85% C10 acid 64 sec. Second fraction composed of 64% C12 acid -1 33 sec. Third fraction composed of 87% Ca acid 2'7 sec. Fourth fraction composed of 89% C14 acid 35 sec. Fifth fraction composed of 90% Cm 35 acid 90 sec. Pure palmitic acid (C16 acid) 1320 sec. 'Pure stearic acid (Cm acid) f 600 sec. Methyl ester of palmitic acid 2400 sec. In concentration of 5 grams per liter: 40 Pure palmitic acid 135 sec. Methyl ester of palmitic' acid 275. sec.
Without wetting agents 24 hours.
These acids from which the wetting agents were derived were obtained by fractionating the cocoanut fatty acids containing acids from Ca to C18, i. e. capronic, caproic, capryllic, lauric, myristic, palmitic, stearic by .distillation. It will be seen that the wetting activity reaches a maximum between C12 and C14 acids. Cu; is almost inactive and Cs on the other side is less active than C12 or C14. Because of the predominance of the C12 and C14. acids in cocoanut oil very good results are obtained by using the fatty acids naturally occurringin cocoanut oil or other nut oils of similar composition such as palm kernel oil. In fact, mixtures of several of these fatty acids, such as the mixture of acids in the proportions in which they occur in cocoanut oil and palm nut oil, seem to yield better results than Application June 17, 1933, Serial No. 676,324
are obtained with the C12 or C14 acids alone.
water soluble as entering into the water layer at the surface or interface of the material to be wetted. Now the wetting agent will be most eflicient, other factors being equal, when the fatty soluble chain and the water soluble chain will be balanced or of equal strength. For instance, if the oil soluble function is much stronger than the water soluble, the molecule will tend to be withdrawn mostly into the oil layer and poorer wetting power will result. If, on the other hand,
the water soluble chain surpasses in power the.
oil soluble chain, a tendency for the withdrawal of the molecule into the water results, again with loss of Wetting power. Thus applying this reasoning to the above table, it may be considered that the C12 and C14 groups are the best balanced of the acids given. My theory finds further confirmation in the action of cbmpounds in which the polar activity is increased by the addition of more hydroxyl groups, as by using diethanolamine in the sulphonation product instead of the mono compound. The sinking power is poorer, being of the order of 171 seconds in the concentration of 1 gram per litre. By increasing these groups still further by using triethanolamine the sinking time is raised to 480 seconds.
In order that my invention may be fully understood, I give the following illustrative example using the naturally occurring cocoanut fatty acids:
210 pounds of cocoanut fatty acids having an average molecular weight of 210 is heated with 67 pounds of monoethanolamine for a fewhours in a still until the acid number determined in alcohol sinks to below 5, the water evolved being allowed to escape. The distillate of water and excess 'monoethanolamine amounts to about 19 pounds. The mass on cooling sets to a pale yellow wax-like substance having a solidification point of 60-65" C., and may be sulphonated directly. This product is slightly soluble in water.
This product may be subjected to the action of sulphuric acid in the following manner:
To 100 pounds of sulphuric acid monohydrate pletely homogeneous, tests are made to determine the water solubility. -As soon as the solubility is complete, the mass is mixed with '75 pounds of ice and neutralized while cooling with suflioient 50% caustic soda to bring the whole to a neutral reaction to litmus. The excess sulphuric acid may also be separated by slight dilution or salted out.
This treatment results, as nearly as can beascertained, in the formation of a predominant quantity of the sulphuric esters in which the sulphur atom is joined to the compound by an oxygen linkage and possibly of some slight quantities of true sulphonated compounds in which the sulphur is attached to the carbon atoms. To the type of reaction with sulphuric acid exemplified by said treatment I apply herein the term sulphation.
The amount of sulphuric acid used in the sulphonation is not critical, except that a large excess, as for example double the amount specified, is detrimental. Furthermore, while the temperature may vary within limits, it should not exceed C. More active sulphonating agents may be used as desired, such as chlor-sulphonic, ethionic acid, oleum, etc. However, I have found that the ordinary sulphuric acid monohydrate is sufliciently active for the purpose. In the condensation products described there is only one hydroxyl group.
Contrary to the sulphonated fatty alcohol series, it has been found that the saturated fatty acids give more active compounds with ethanolamine followed by sulphation than the unsaturated. Inert solvents may also be used in the treatment as, for example, trichlorethylene, carbon tetrachloride, etc., but it has been my experience that the advantage so gained does not usually warrant the expense entailed by the use of solvents.
The sulphated products of my invention are an almost white, thick paste, having remarkable detergent and emulsifying properties. These products when used in the dye bath even in very high dilutions give thorough and even dyeing and an excellent feel to the goods. The product is fast to lime, disperses lime soaps and is fast to acid and alkali. It may be incorporated with soap as a soap assistant or it may be used as an emulsifying agent in greases, creams and cosmetics, in securing, as a penetrating agent, in the tanning industry to accelerate tanning, deoiling, dehairing, etc. It may also be used with insecticides to increase their covering power in aqueous form and in such capacity it is termed an insecticide promoter. The product may be dried in a vacuum and reduced to a fine white powder.
In lieu of monoethanolamine, the monopropan01 amines and monobutyl amines may be used.
