METHOD OF OBTAINING EMULSIFIER Russian patent published in 2008 - IPC C07C303/32 C08F8/44 C07C303/24 C07C305/06 C08F8/36

Abstract RU 2340599 C1

FIELD: chemistry.

SUBSTANCE: emulsifier is obtained by sulfating oxyethylated alkylphenol of general formula RC₆H₄(OC₂H₄)_nOCH₂CH₂OH, where R is alkyl with 8-10 carbon atoms, and n=3-19, with concentrated sulfuric acid with heating with further neutralisation of sulfomass with base water solution, characterised by the fact that sulfating is carried out with molar ratio of oxyethylated alkylphenol and sulfuric acid equal 1:(1-2) during 36-37 minutes, neutralisation of sulfomass with base water solution being carried out during 3-7 minutes.

EFFECT: intensification of emulsifier obtaining process and increase of content of target product weight part.
