Patent GB-443265-A (GB)
Title: Improvements in or relating to the manufacture and use of organic condensation products particularly for the treatment of textiles
Filed: 1935-01-16
Abstract: Products suitable for use in the treatment of textiles are obtained by condensing degradation and clearage products of albumens &c. with compounds of the general formula <FORM:0443265/IV/1> where X = OR<3> or <FORM:0443265/IV/2> and at least one of the radicles R<1> to R<4> is a high molecular alkyl radicle and the remainder may be hydrogen or any hydrocarbon residue.  Suitable compounds are chloracetic acid lauryl ester, a -bromopropionic acid cetyl ester, a -bromolauric acid oleyl ester, chloracetic acid N-laurylamide, chloracetic acid-(N-cetylphenyl)-amide, and a -bromolauric acid oleyl amide. The albumen clearage products may be leucyl leucine, silk fibroin, lysalbinic acid, and degeneration products of glue, casein, leather, horn, &c.  The condensation is carried out under slightly alkaline conditions, with vigorous stirring, and at temperatures between -20 DEG  C. and 150 DEG  C., usually at 5--35 DEG  C., it being sometimes advantageous to allow the temperature to rise to 70--80 DEG  C.  An example is given using the sodium salt of lysalbinic acid and chloracetic acid - N - dilaurylamide.  The product when added to a washing bath or to an alkaline bath is stated to have a cleansing, wetting and levelling effect.  The condensation products may be employed with fat solvents and other known textile improving agents. The Specification as open to inspection under Sect. 91 includes the production of condensation products with the use as the second reagent of compounds in which the group --C(R<1>R<2>) of the above formula is absent, and it also includes as the second reagent compounds of the general formula, --CO--R<5>--Y--R<6>, where R<5> is an alkylene or arylene residue and R<6> any hydrocarbon residue, at least one of these residues containing an aliphatic chain of at least eight carbon atoms, and Y represents oxygen or sulphur or the groups SO2, NR<7>, CONR<7>, NR<7>CO or NR<7>SO2, in which R<7> is hydrogen or any hydrocarbon residue; and it refers to the following specific compounds falling under the above general formul : chlorocarbonic acid cetyl ester, dichlorocarbonic acid ester of 1.18-stearylene glycol, dilauryl urea chloride, o -butyl- or cyclohexyl ether of cupric acid chloride, lauroxyacetic acid bromide, o -piperidine-undecylenic acid chloride, N-laurylphenylamino acetic acid chloride, a -phenyl thiolauric acid bromide, b -cetylthiopropionic acid chloride, dodecylsulphoacetic acid chloride, N-dioctyl-adipic acid amido acid chloride, N-lauroylphenylaminoacetic acid chloride, and N, N-dodecyl-p-toluene-sulphonylamino acetic acid chloride; it also contains examples of the production of a condensation product from lysalbinic acid and N-lauroyl-phenylamino acetic acid chloride for addition to dyebaths to give level dyeings, and of the production of a condensation product, for addition to washing baths, of the degenerative products of casein or gelatine and the acid chloride obtained by condensing the disodium salt of thioglycollic acid with dodecyl chloride, oxidizing the sulphide obtained with nitric acid, and converting the dodecylsulphoacetic acid into the acid chloride; and it also states that the condensation products may be employed with fat solvents or other known textile improving agents.  This subject-matter does not appear in the Specification as accepted.
