Rubber auxiliary M (CAS: 149-30-4) production methods and uses
O-nitrochlorobenzene can be reduced to o-aminothiophenol by reaction with reducing agent sodium bisulfide, sodium polysulfide or hydrogen sulfide. Rubber accelerator M (CAS: 149-30-4) is further prepared with the reaction of carbon disulfide. Some reactions of this method have a longer reaction time (sodium bisulfide is about 20h), but all can be carried out under normal pressure or low pressure, also known as normal pressure method. Diphenylthiourea as raw material.

Sodium polysulfide
Sodium polysulfide is a general term for salts with the formula Na2Sx, where x = 2 to 5. The species Sx2−, called polysulfide anions, include disulfide (S22−), trisulfide (S32−), tetrasulfide (S42−), and pentasulfide (S52−). In principle, but not in practice, the chain lengths could be longer.
