The invention concerns a process for the manufacture of surface-active sulfophosphoric-acid-(partial)-alkyl-esters and their alkali-, alkaline earth-, ammonium- and amine salts by the sulfonation of phosphoric acid esters and subsequent hydrolysis of the sultone intermediate stages formed.

Surface-active sulfophosphoric-acid-(partial)-alkyl-esters

A process for preparing surface-active, saturated sulfophosphoric acid-(partial)-alkyl esters and their alkali metal, alkaline earth, ammonium and/or amine salts by the sulfonation of saturated phosphoric acid-(partial)-alkyl esters and then hydrolysis of the sulfonated phosphoric acid esters formed.

Surface-active, saturated sulfophosphoric acid-(partial)-alkyl esters

Sulfited fats prepared by oxidation of fats with oxygen-containing gas mixtures and simultaneous or subsequent sulfitation using alkali and/or ammonium hydrogen sulfites, wherein the fats used are mixtures containing

Sulfited fats as oiling agents for leather and skins

Sulfited fats

This invention relates to sulfonated lubricating agents for leather and furs. More specifically, this invention relates to a process for the production of sulfonated lubricating agent for leather and tanned furs consisting of the steps of:

Preparation of sulfonated lubricating agents for leather and furs

A leather fatliquoring agent and a process for its use in which the agent is a sulfosuccinic (C.sub.12-24 fatty residue) ester and an anionic or nonionic emulsifier. The agent is stable in the presence of tanning liquor electrolytes.

Leather fatliquoring agents combinable with tanning and retanning

A process for the sulfonation of certain fat and oil mixtures, the product of such process, and a method for using such product as a leather tanning stuffing agent, the certain fat and oil mixtures comprising (A) 20-80% by weight of at least one C.sub.8-24 -fatty acid glycerol ester having an iodine number above 20, and (B) the balance q.s. to 100% by weight of at least one C.sub.1-4 -aliphatic monoalcohol ester of a C.sub.8-24 -fatty acid having an iodine number of 50-100.

Sulfonation of fats and oils

Sulfonated lubricating agents for leather and furs process therefore
