Abstract: New dissociable, nonionic, surface active polycarbonate adducts have formula RX left brace (CH2CH2O)k-COO-(CH2CH2O)p- n-H right brace m (I) (where RX is the residue of an 8-22C alcohol (a), an 8-22C prim. or sec. amine (b), an alkylphenol (c) or of a 1-20 x oxyethylation prod. of (a) to (c); k is a +ve integer, including 0, and p is a +ve integer >=1 provided that if k = 0, p is >=1 and k + p has average statistical value 1-20, esp. 4-15; n has average statistical value 1-10 and m is 1 or 2). (I) are used as wetting agents, foaming agents and emulsifiers. (I) can be degraded biologically. (I) dissociate at carbonate gp. under acid or base action, and lose their surfactant activity. This property can be made use of in the planned breaking of emulsions or other surfactant compsns.

Abstract: Fatty acid nitriles of formula R1(R2,R3)-CN, (I), (where R1, R2 and R3 are 3-23 C aliphatic hydrocarbyl opt. substd. by an OH gp.) and glycerol, are prepd. by contacting mono-, di- and/or tri-glycerides of formula (II), in the liq. phase, with a gaseous NH3 stream, used in proportions >=200 l/kg.hr. of (II), opt. in the presence of an inert gas, at 220-300 degrees C, in the presence of Pb, Zn, Cd, Sn, Ti, Zr, Cr, Sb, Mn, Fe, Ni or Co carboxylates or sulphonates as catalysts. The prod. mixt. discharged is subjected to a phase-separation, into a fatty acid nitrile phase and a glycerol/water phase. (I) are intermediates for prim. amines and quat. ammonium cpds., which can be used as textile auxialiaries, flotation agents and cation-active surfactants. Glycerol is used in cosmetics and food industry, in prepn. of explosives, and as solvent, textile auxiliary and additive to heat- or power transfer fluids. Process allows quick direct conversion of natural fats or oils to (I) and glycerol. High yields are obtd., e.g. 93-96% of (I) and up to 95% glycerol. (I) contains 2 wt.% free fatty acids and 10 wt.% fatty acid amide by-prods.

Abstract: The invention relates to novel O/W emulsifiers obtainable by reacting one mole of esters of wool wax acids and glycerol, in particular partial esters, with 0.5 to 30 moles of ethylene oxide, a process for the preparation of these novel products and cosmetic agents containing these in an amount of 1 to 15% by weight, based on the total formulation.

Abstract: A process for the purification of esters, which contain residues of dissolved and/or undissolved alcohols, is described. The purification of the esters containing alcohols is achieved by treating the esters, in the liquid state, with an effective amount of water-soluble polysaccharide derivatives in the solid state.
