Title: Improvements in the treatment of rubber and similar oxidizable materials
IPC: C08K5/205
Filed: 1938-09-06
Abstract: 508,442. Preserving rubber, oils, &c. UNITED STATES RUBBER PRODUCTS, Inc. Sept. 6, 1938, No. 26010. Convention date, Sept. 11, 1937. [Class 70] [Also in Groups IV and III] Rubber and the like and other oxidizable materials, e.g. unsaturated fatty oils, essential oils, petroleum oils and their derivatives such as gasolines, soaps, aldehydes and synthetic resins, are preserved by incorporating a small proportion, e.g..1 to 5 per cent of a compound having the general formula where R1 is an aryl group R2 is an arylene group, and Y is a carboxyl radical, the hydrogen atom of which is replaced by an alkyl, aryl or aralkyl group and which may be substituted or unsubstituted. The compounds may be formed, for example, by the interaction of a primaryamino-substituted diarylamine and a chlorocarbonic ester, also known as a chloroformic ester. In an example, 20 gms. of p-aminophenyl p-tolylamine dissolved in 150 c.c. of alcohol are mixed with 145 gms. of ethyl chlorocarbonate dissolved in 50 c.c. of alcohol. 15 gms. of sodium acetate dissolved in 30 c.c. of water are added and the mix is refluxed for 1¢ hours, cooled and diluted with one-half volume of water. The crystals separating are purified by solution in acetic acid and reprecipitate by dilution with water. The product is believed to have the formula and may be termed p-(p-tolylamino)-phenyl urethane. A list of examples of primarysecondary aromatic amines derivatives of which constitute the preservatives of the invention and examples of substituted carboxyl groups are given in the Specification.

Title: Dyeing of nitrogenous fibrous material
IPC: B23F23/12
Filed: 1959-07-29
Abstract: Nitrogenous fibres, such as wool, silk and polyamide fibres, are dyed by treatment in an acid bath containing a sulphonated copper phthalocyanine and an auxiliary compound containing at least one basic nitrogen atom to which is attached at least one radical containing a polyglycol ether chain, the compound containing in its molecule at least three groups of the structure <FORM:0860908/IV(c)/1> and at least four carbon atoms not belonging to such a group, the pH of the bath being raised to above 6, e.g., 6,5-9, after the fibres have absorbed the required amount of dye. The sulphonated copper phthalocyanines may contain, two, three or four sulphonic acid groups, and if desired other substituents such as halogen atoms or sulphonic acid amide groups.  Mixtures of sulphonated copper phthalocyanines with reactive dyes or with solubilized metal complex azo dyes may be employed.  Numerous auxiliary compounds, which are condensation products of an alkylene oxide with a compound containing at least one basic primary or secondary amino group or one basic tertiary amino group and in addition an alcoholic hydroxyl group, or salts or quaternary ammonium salts of such condensation products, are specified.  The dyebath is acidified preferably with acetic acid, and dyeing is effected at or near or above 100 DEG C.  On completion of dyeing, elevation of the pH is effected by the addition of an alkaline substance, such as ammonia, hexamethylenetetramine, ethanolamines, alkali metal ortho- or poly-phosphates or mixtures thereof to the dyebath. This after-treatment is also preferably effected at an elevated temperature.  Examples describe the dyeing of wool and a wool-polyamide fibre mixture.
