Abstract

Acetone arabite, acetone mannite, acetophenone glycerine, and cyclohexanone glycerine are prepared by condensation of the respective ketones and polyvalent alcohols; 2 : 2-methylpentamethylene - 4 - oxymethyldihydrodioxol is prepared by condensing methyl-cyclohexanone with glycerine; cyclohexanone glycerine phthalate by esterifying cyclohexanone glycerine at the free hydroxyl group; acetone glycerine butyl ether and acetone glycerine benzoate by etherifying and esterifying acetone glycerine at the free hydroxyl group; oleyl monoglycol ether and octyl monoglycerine ether by the action of alkyl chlorides on the sodium glycol or glycerine compounds.ALSO:Gelatine, glue, casein, albumen, and the like masses are softened by high molecular aliphatic, cycloaliphatic, or fatty aromatic alcohols containing at least 6 carbon atoms in the molecule and less hydroxyl groups than carbon atoms or esters of such alcohols, or ethers of high molecular aliphatic cycloaliphatic or fatty aromatic alcohols containing at least 6 carbon atoms, or cyclic hydroxyl substituted ethers which may contain several oxygen atoms in the ring and may have one or several side chains or their ethers or esters. The softening agents may be used as emulsions, fatty alcohol sulphonates being suitable emulsifiers, or as solutions in e.g. water soluble mono- or polyhydric alcohols or their ethers or esters, or partly water soluble solvents such as butanol, or ketones. They may be used in conjunction with hygroscopic organic or inorganic compounds. As examples of such softeners are octyl, oleic, benzyl, octadecyl, cetyl, and lauryl alcohols, the alcohols obtained by reducing the fatty acids of coconut or palm kernel oil, the unsaturated alcohols in sea animal oils, cyclohexanol and its homologues, the alcohols obtainable by reducing naphthenic acid, octylbutyl ether, laurylmonoglycol ether, adipic-acid-dicyclohexylester, lauric - acid - oleylester or dodecylsulphonate, cetyl ricinoleate, oleyl acetate, oleyl monoglycol ether, octyl monoglycerine ether, acetone-glycerine, acetonearabite, acetonemannite, acetophenoneglycerine, cyclohexanone glycerine 2.2.methyl pentamethylene-4-oxymethyl dihydrodioxol, acetone glycerine benzoate, the hydrogenation products of furfurol, e.g. furfuryl alcohol and tetrahydrofurfuryl-alcohol, tetrahydrofurfurylacetate, furfurylbenzoate, cyclohexanone glycerine-phthalate, furfurylethylether, and acetoneglycerinebutylether. In examples: (1) gelatine contains 8 per cent of oleic alcohol dissolved in methyl alcohol or 10 per cent of cetylricinoleate dissolved in isopropyl alcohol, (2) casein contains 5 per cent oleylacetate dissolved in a butanol-isopropyl alcohol mixture or 10 per cent cetylalcohol and octadecylalcohol in cetylricinoleate, (3) gelatine contains 7,5 per cent tetrahydrofurfuryl alcohol or cyclohexanone glycerine phthalate or acetone glycerine, (4) casein contains acetone glycerine benzoate or acetone mannite dissolved in butanol or as an emulsion, (5) a gelatine mass for duplicating stencils comprises, in parts, aqueous gelatine solution 23,5, cetyl alcohol and octadecyl alcohol 6, oleylmonoglycol ether 7,5, octylmonoglycerine ether 2, 2-2 methylpentamethylene-4-oxymethyldihydrodioxol 2, bolus 3, water 12. This mass is applied in the usual manner to a support, e.g. Japan tissue paper. Of the softening agents, acetone arabite, acetone mannite, acetophenone glycerine, and cyclohexanone glycerine can be prepared by condensation of ketones with polyvalent alcohols, 2.2-methylpentamethylene - 4 - oxymethyl di-hydrodioxol may be prepared by condensing methyl-cyclohexanone with glycerine, cyclohexanone glycerine phthalate by esterifying cyclohexanone glycerine at the free hydroxyl group, acetone glycerine butyl ether and acetone glycerine benzoate by etherifying and esterifying acetone glycerine at the free hydroxyl group, oleyl monoglycol ether and octyl monoglycerine ether by etherification as by the action of alkyl chlorides on the sodium glycol or glycerine compounds.
