Title: Improvements in or relating to softening, plasticising, and like agents and processes
IPC: C08K5/101
Filed: 1931-10-07
Abstract: Esters (free from sulpho and amino groups) of cyclohexanol or its homologues with aliphatic or hydrocyclic monocarboxylic acids containing more than six carbon atoms are used as softening, smoothing or revivifying agents for textiles and leather, or as plasticizers in cellulose ester and ether compositions, or as constituents of lacquers or cleansing, polishing or lubricating compositions.  For the treatment of textiles and leather, the esters may be used in solution in an organic solvent such as benzine, turpentine, pyridine or a hydrogenated naphthalene; alternatively, the esters may be emulsified in water, preferably with the aid of emulsifying agents such as soaps, sulphonated oils, or ester salts or xanthogenates of higher alcohols.  As textiles which may be treated, mention is made of raw, woven or spun silk, artificial silk, wool, and cotton.  The following examples are given:--(1) a revivifying agent for textile fibres is prepared by mixing methylcyclohexyl palmitate with turkey red oil; (2) an ordinary polishing wax of unspecified composition is modified by replacing a part of the wax constituents by cyclohexyl montanate; (3) a composition for cleaning metals is prepared by mixing cyclohexyl naphthenate or a homologous ester with silicious chalk and a volatile solvent; (4) films are prepared from a solution of nitrocellulose in butyl acetate and ethyl alcohol containing methylcyclohexyl palmitate; (5) a plastic composition comprises cellulose acetate and nitrate, rubber, ethyl lactate, butyl acetate, cyclohexanone, cyclohexyl acetate, and an ester as defined above.  Mention is made also of the inclusion of the esters in cellulose ester and ether lacquers containing rubber.  The use of esters of cyclohexanol and its homologues with coco-nut oil or palm-kernel oil acids, abietic acid, and oleic acid is referred to. The Specification as open to inspection under Sect. 91 describes broadly the use, for the purposes stated above, of esters of cyclic alcohols with "high molecular" monocarboxylic acids of the aliphatic, aromatic, hydrocyclic or heterocyclic series, and refers specifically to the use of the borneol, fenchol, and terpineol esters of coco-nut oil and palm-kernel oil acids, bornyl and terpinyl naphthenates, and bornyl montanate and stearate.  It includes also an example, corresponding to example 3 above, in which terpinyl naphthenate replaces the cyclohexyl naphthenate or its homologue, and a further example in which a plastic mass is prepared from nitrocellulose, alcohol, and bornyl stearate.  Also, it refers to the esters as emulsifying agents.  This subject-matter does not appear in the Specification as accepted.  Esters.--Examples are given of the preparation of typical esters, as follows:--(1) cyclohexyl palmitate is prepared by heating cyclohexanol and palmitic acid in the presence of sulphuric acid; methylcyclohexyl palmitate and oleate are prepared similarly; (2) cyclohexyl abietate is prepared by heating cyclohexanol and abietic acid in the presence of boric acid; (3) cyclohexyl montanate is prepared from cyclohexanol and montanyl chloride, which is obtained from raw or purified montanic acid and thionyl chloride; (4) cyclohexyl naphthenate is prepared from cyclohexanol and naphthenyl chloride, which is prepared from naphthenic acid and thionyl chloride.ALSO:Esters (free from sulpho and amino groups) of cyclohexanol or its homologues with aliphatic or hydrocyclic monocarboxylic acids containing more than six carbon atoms are used as softening, smoothing or revivifying agents for textiles and leather, or as constituents of lacquers or cleansing, polishing or lubricating compositions.  For the treatment of textiles and leather, the esters may be emulsified in water, preferably with the aid of emulsifying agents such as soaps, sulphonated oils, or ester-salts or xanthogenates of higher alcohols.  The following examples are given: (1) polishing wax is modified by replacing a part of the wax constituents by cyclohexyl montanate; (2) a composition for cleaning metal is prepared by mixing cyclohexyl naphthenate or a homologous ester with silicious chalk and a volatile solvent. Mention is made also of the inclusion of the esters in cellulose ester and ether lacquers containing rubber.  The use of esters of cyclohexanol and its homologues with coco-nut oil or palm-kernel oil acids, abietic acid and oleic acid is referred to.

This subject-matter does not appear in the Specification as accepted.ALSO:Esters (free from sulpho and amino groups) of cyclohexanol or its homologues with aliphatic or hydrocyclic monocarboxylic acids containing more than six carbon atoms are used as plasticizers in cellulose ester and ether compositions.  Specified acids from which suitable esters may be prepared are oleic, palmitic, montanic, naphthenic and abietic acids, and the acids of coconut oil or palm-kernel oil.  An example describes a plastic composition comprising cellulose acetate and nitrate, rubber, ethyl lactate, butyl acetate, cyclohexanone, cyclohexyl acetate, and an ester as defined above.  The use of esters of cyclohexanol and its homologues with coconut oil or palm-kernel oil acids, abietic acid, and oleic acid is referred to.
