    Abstract: A process is disclosed for stuffing, fulling and waterproofing leathers and pelts by using en-adducts of maleic acid anhydride to either unsaturated fatty acids containing 12-24 C atoms, their C1-C20 alkyl ester or C2-C20 alkenyl esters, triglycerides, amides, mono- or di-(C2-C4 alkanol) amides, mono- or dipolyetehr amides or polyether esters; or by using en-adducts derivatized partially or completely by conversion into amides or esters with amines or alcohols.

    Abstract: Use of homo-or copolymerisates based on monoethylenically unsaturated dicarboxylic acid anhydrides which can be obtained through the radically initiated polymerisation of a) 30 - 100 mol.% of one or more monoethylenically unsaturated dicarboxylic acid anhydrides with 4-10 C atoms; b) 0 - 70 mol.% of one or more vinyl aromatics of general formula (I) wherein R , R and R represent hydrogen, methyl or ethyl and k has a value of 1 or 2; c) 0 - 70 mol.% of one or more vinyl esters of C1-C8 carboxylic acids; d) 0 - 50 mol.% of one or more C2-C6 olefines; and e) 0 - 30 mol.% of one or more monoethylenically unsaturated C3-C5 carboxylic acids, B) amines or alcohols or mixtures of such amines and alcohols for stuffing and fulling leathers and fur pelts.

    Abstract: In anti-foams for the paper industry, based on oil-in-water emulsions, the oil phase makes up 5 to 50 % by weight of the bulk of the emulsion and contains (a) an alcohol having at least 12 carbon atoms, fatty acid esters of alcohols having at least 22 carbon atoms and C1- to C36-carboxylic acids, distillation residues which are obtainable in the production of alcohols having a higher carbon number by oxo synthesis or by the Ziegler process and which may be alkoxylated, mixtures of the said compounds and/or (b) a fatty acid ester of C12- to C22-carboxylic acids with monohydric to trihydric C1- to C18-alcohols and, if appropriate, (c) a hydrocarbon having a boiling point above 200 DEG C or fatty acids having 12 to 22 carbon atoms in combination with (d) 1 to 80 % by weight of polyglycerol esters which can be prepared by an at least 20% esterification of polyglycerol mixtures which contain, as essential constituents, diglycerol, triglycerol, tetraglycerol and, if appropriate, more highly condensed polyglycerols, with saturated or unsaturated C12- to C36-fatty acids. i

    Abstract: Preparation of low-temperature-stable alkanolic-aqueous solutions of polyethersulphonates of the general formula I R-(O-A)n-SO3M I in which R represents an alkyl or alkenyl group having 8 to 25 carbon atoms or an alkylphenyl group having 8 to 18 carbon atoms in the alkyl radical, A denotes a 1,2-alkylene group having 2 to 4 carbon atoms, n has a value of between 1 and 15 and M represents an alkali metal cation or an ammonium cation which can be substituted by C1-C4-alkyl groups or C1-C4-hydroxyalkyl groups, by reacting polyether halides of the general formula II R-(O-A)n-X II in which X represents chlorine or bromine, with an aqueous solution of an alkali metal sulphite or ammonium sulphite and diluting the reaction solution with a C4-C8-alkanol, by heating the reaction mixture after the reaction to 60 to 150 DEG C at 1 to 5 bar and separating the mainly aqueous phase which is formed in this process. The low-temperature-stable solutions of the polyethersulphonates I are used as surfactant solutions in tertiary oil drilling.

    Abstract: Gasoline and diesel fuels contain minor amts. of: (a) an ethoxylated, propoxylated or butoxylated mono- or polyhydroxy cpd. with a no.-av. molecular wt. of 500-6000; and (b) an NTA or EDTA imide deriv. of formula (I): (where Q = CH2COX or CH2CH2N(CH2COX)2; X = NHR or X+X = NR; R = 7-18C aliphatic gps. (same or different)). Component (a) is specifically derived from an alcohol of formula R(OH)n, where n = 1-4 and R = 1-20C alkane, by reaction with butylene oxide or a combination of propylene oxide and butylene oxide in a ratio of 5:95 to 95:5. The (a):(b) wt. ratio is 5:1 to 1:3. The fuels contain 0.01-0.3 wt.% (a) + (b).

    Abstract: Polyglycerine fatty acid ester mixts. (I) obtd. by partial esterification of polyglycerine mixts. can be used as emulsifiers in cosmetic and pharmaceutical prepns. The polyglycerine mixts. consist of 0-5 wt% monoglycerine, 15-40 wt% diglycerine, 30-55 wt% triglycerine, 10-25 wt% tetraglycerine, 0-15 wt% pentaglycerine, 0-10 wt% hexaglycerine and 0-5 wt% higher polyglycerines and are partially esterified to a deg. of 20-70% with at least one unsatd. 16-22C fatty acid contg. up to 10 wt% satd. 16-22C fatty acids. USE/ADVANTAGE - (I) can be used as water-in-oil emulsifiers in cosmetic and pharmaceutical prepns. with considerably improved storage stability with the cosmetics and pharmaceuticals emulsified in them, than is usual with water-in-oil emulsions which are more difficult to stabilise than oil-in-water emulsions. Using (I) it is possible to use lower concentrations to achieve the same effect than is the case with conventional emulsifiers. There is no need to bleach (I) after they have been prepd.; thus prods. using (I) are better tolerated by the stain and the body.
