Abstract

541,682. Acid amide derivatives. ALFRAMINE CORPORATION. Feb. 27, 1940, No. 3625. Convention date, March 1, 1939. Samples furnished. [Classes 2 (iii) and 15 (ii)] [Also in Group VI] Aliphatic aldehydes containing one to five carbon atoms are condensed with fatty acid alkylolamides having the formula R.CO- (NHC 2 H 4 )nNHCyH 2y OH in which R is an aliphatic chain having at least 7 carbon atoms, y is a number from 2 to 4 and n a number 0 to 3. The fatty acid alkylolamides may be derived from fatty acids or esters such as sperm oil, cod liver oil and hardened cod liver oil by condensation with the appropriate alkylolamine or the fatty acid or ester may be condensed with ammonia and then re-acted with alkyleneoxides or chlorhydrins. Butyraldehyde and exotonaldehyde may be used for re-action with the alkylolamides. The products, by sulphonation are converted into soluble wetting, washing and foaming agents. They may be used in fire extinguishers and in shampoos. The unneutralized sulphonic acids are suitable for breaking oil emulsions of fatty acids, fats and mineral oils. In examples : (1) monoethanolamine is condensed with castor oil and coconut oil, the products condensed with formaldehyde and then sulphonated : (2) castor oil is condensed with hydroxyethylethylenediamine or hydroxypropylethylenediamine, the product re-acted with formaldehyde and sulphonated : (3) castor oil is condensed with monoethanolamine, the product re-acted with acetaldehyde and sulphonated : (4) olive oil is condensed with isobutanolamine, the product re-acted with formaldehyde and sulphonated: (5) palm oil fatty acid is condensed with hydroxyethylethylenediamine and the product re-acted with formaldehyde : (6) the product of example 5, dissolved in acetic acid is used in neutral or acid dyebaths, containing sulphates to secure full dye penetration : (7) the unsulphonated product from example 2 is used in carbonizing wool, the latter retains its capacity to absorb dyes. The Specification as open to inspection under Sect. 91 comprises also the use of fatty acid alkylolamides having the formula R.CO- (NHCx H 2x )nNHO y H 2y OH wherein R and n are as above defined and x and y are a number from 2 to 5. In a further example, viscose crepe containing titanium oxide is softened by treatment in a bath containing the product of example 5 and lactic acid followed by calendering. In another example, tallow is re-acted with hydroxypropylethylenediamine and acetaldehyde, and the product is used together with lactic acid in a bath for the treatment of acetate artificial silk. This subject-matter does not appear in the Specification as accepted.
