It is another object of this invention to provide textile material having improved properties.
Other objects and advantages of this invention will be apparent from the following description and appended claims.
The novel carbamates of this invention are carbamates of an ethylene oxide adduct selected from the group consisting of 1. an ethylene oxide adduct of a fatty acid containing from 12 to 28 carbon atoms,
2. an ethylene oxide adduct of a fatty alcohol containing from 12 to 28 carbon atoms,
3. an ethylene oxide adduct of a fatty amine containing from 12 to 28 carbon atoms,
4. an ethylene oxide adduct of an amide of a fatty acid containing from 12 to 28 carbon atoms,
5. an ethylene oxide adduct of a partial fatty acid ester of a polyhydric alcohol containing from 3 to 6 carbon atoms and from 2 to 6 hydroxyl groups, said fatty acid containing from 12 to 28 carbon atoms, and
6. a partial ester of a fatty acid containing from 12 to 28 carbon atoms and an adduct of ethylene oxide and a polyhydric alcohol containing from 3 to 6 carbon atoms and from 2 to 6 hydroxyl groups.
A preferred class of carbamates of this invention are carbamates of ethylene oxide adduct selected from the group consisting of (5) and (6).
The carbamates of this invention contain at least one oxyethylene group, at least one fatty group containing from 12 to 28 carbon atoms, and at least one group wherein R and/or R, are hydrogen or methylol. Accordingly, the carbamates of this invention may be described as esters of carbamic acid, N-methylol carbamic acid, or N,N-dimethylol carbamic acid and the above defined ethylene oxide adducts. The carbamates wherein R, to R, are both hydrogen are useful as intermediates for the preparation of textile treating agents by reacting the carbamate with formaldehyde to introduce one or more methylol groups. The carbamates of this invention wherein R and/or R are methylol are useful as textile treating agents which impart a durable and permanent softness to textile materials when applied thereto.
The carbamates of this invention may be prepared by reacting one or more of the ethylene oxide adducts described herein with urea or with an alkyl carbamate such as ethyl or methyl carbamate. The reactions are illustrated by the following equations:
o i organic-OH HJVHNH, NH, organic- NH,
These two well-known methods of forming carbamates are described in detail in the article by Adams et al. published in Chemical Reviews, Volume 65, pages 567-602, 1965. The disclosure of this article is hereby incorporated into this application by reference. Briefly, the reaction may be carried out by heating a mixture of urea or alkyl carbamate and an ethylene oxide adduct to a temperature in the range of from about 1 10C. to about 200C. Catalysts, such as heavy metal salts of weak organic acids, zinc chloride, cobalt chloride, lead acetate, cupric acetate, boron trifluoride, aluminum isopropoxide, dibutyltin dilaurate, and dibutyltin oxide may be used to shorten the reaction time and increase the yield. The degree of carbamylation may be controlled by varying the amounts of ethylene oxide adduct and carbamylating agent used. For example, the reaction of three mols of urea with one mol of an ethylene oxide adduct containing six hydroxyl groups will result in the formation of a carbamate containing an average of three carbamate groups. The carbamates of this invention may also be prepared by reacting an ethylene oxide adduct described herein with phosgene to form a chloroformic ester which then may be reacted with ammonia to give the carbamate. Other methods for preparing the carbamates of this invention will be readily apparent to one skilled in the art. The methylolated carbamates of this invention may be prepared by reacting the carbamate with formaldehyde, paraformaldehyde, or other convenient source of formaldehyde.
The ethylene oxide adducts which may be used to prepare the carbamates of this invention are known compounds. U.S. Pat. Nos. 1,959,930; 1,970,578; and 2,002,613, the disclosures of which are hereby incorporated hereinto by reference, disclose the preparation of ethylene oxide adducts which may be used to prepare the carbamates of this invention. Briefly, the ethylene oxide adducts may be prepared by reacting ethylene oxide with the appropriate fatty alcohol, fatty acid, fatty amine, fatty amide, or ester of fatty acid and a polyol or by reacting a fatty acid with an ether of ethylene oxide and a polyol.
