METHOD FOR OBTAINING SULFUR-CONTAINING ORGANIC COMPOUNDS Russian patent published in 2008 - IPC C07C319/22 C07C321/18 C07C321/20

Abstract RU 2333904 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the field of synthesis of sulfur-containing organic compounds, which can be used in production of additives to lubricating oils. Sulfur-containing compounds are obtained by interaction of norbornene, endo- or exodicyclopentadiene with elemental sulfur in presence of 0.5-2.0% from the weight of the said compounds of catalyst, i.e. 1-(N,N-dimethylaminomethyl)-benzotriazole. The process is carried out at 125-130°C. The invention allows for increasing output of target product to 85-89.9%.

EFFECT: increased output of sulfur-containing organic compounds.
