A method for the production of petroleum - sulfonates, the thereby resulting products and their use for the preparation of micro - emulsions

摘要

P sulfonates oil are obtained by reaction with a sulfonating agent with a heavy hydrocarbon feedstock beforehand partially hydrogenated of modes is to reduce the sulphur content, without excessively reducing the content of aromatic hydrocarbons. / p & & p & these sulfonates can be used as a surfactant - the active agents, for example for the manufacture of microemulsions. / p
