摘要:
Alpha-olefins are dimerised to form vinylidene olefins, which are then isomerised and reacted with CO/H2 under OXO conditions or reacted directly with CO/H2 under OXO conditions to give mid- to near-mid chain branched alcohols. These branched-chain alcohols are feedstocks for the production of alkyl sulphate, alkyl ethoxy sulphate, and alkyl carboxylate surfactants and other surfactants.

摘要:
Disclosed are ethylenically unsaturated amine salts of sulfonic, phosphoric and carboxylic acids. The salts are surface active agents which are especially useful in emulsion polymerization reactions.
摘要:
The invention relates to amphiphilic compounds of general formula (I), (R?1, R3 = C¿1-C22 hydrocarbon radical, R2 = spacer, X, Y = functional groups, Z = 1 to 10) with at least two hydrophilic and at least two hydrophobic groups ont the basis of amides. The amphiphilic compounds of this invention are highly surface-active and are suitable in particular as emulsifiers, demulsifiers, detergents, dispersants and hydrotropics in industry and household, e.g. in the fields of metalworking, ore extraction, surface treatment, washing and cleaning, cosmetics, medicine and foodstuff processing and preparation.
摘要:
A high concentration, aqueous liquid surfactant composition is disclosed, comprising at least one amphoteric or anionic surfactant and a liquid stabilizing amount of at least one liquid-stabilizing agent. The liquid stabilizing agent is a succinic acid derivative, glutaric acid derivative or a combination thereof. The composition is pourable and pumpable at ambient room temperature.
