Product Category Product Name new non-nitrosamines / nitrosamines security accelerator ZBEC, TBzTD, ZDTP, PPD rubber vulcanizing agent sulfur powder (200 mesh), DTDM, 201 phenolic curing resins, phenolic curing resin 202, 2056 curing resin, HVA -2, DCP predispersion vulcanizing agent: DTDM-80, TCY-70A, TCY-70E, IS60-80, S-80, S-80 (SBR), S-80 (NBR) pre-dispersion accelerator: ZDMC -80, ZDEC-80, ZDBC-80, ZBEC-70, TDEC-70, TDEC-75, ZDTP-50, MBT-75, MBT-80, MBTS-75, MBTS-80, ZMBT-80, DPTT-70 , TETD-75, TMTD-80, TMTM-80, TBzTD-70, TBBS-80, NOBS-80, CBS-80, ETU-80, DETU-80, DPG-80, DPG-80, DOTG-70, HEXA -80 pre-dispersion foaming agent: AC-75, OBSH-75 Additional pre-dispersion: CTP-75, CTP-80, MB-80, CaO-80, TiO2-80, HMMM-80, a resorcinol - 80 rubber vulcanization accelerator M manufacturing processes to aniline production of rubber accelerator M, reaction time is longer, generally have about 5h, in order to shorten the reaction time, the American Cyanamid patent proposes a catalyst to accelerate the reaction, increase product yield rates and methods of quality. The catalyst used was: phosphorus pentasulfide, phosphorus trisulfide, tetrasulfide phosphorus heptasulfide phosphorus, red phosphorus, mercury and other accelerator M (MBT) price, in the presence of a catalyst, the reaction speed can be increased by 4 times. Side of an updated, economical and convenient method for the synthesis accelerator M, Cyanamid's patent to study the synthesis of byproducts benzothiazole accelerator M method, between the benzothiazole accelerator M and a balance . The above reaction process can be carried out at atmospheric pressure, the proportion of the sulfur and benzothiazole is 0.9: 1-1.3: 1 (mol) Wei Lin accelerator M (MBT), the optimal ratio of 0.95: 1-1.1: 1 (mol ); The reaction temperature was 220-260 ℃, the optimal reaction temperature was 240 ℃. Pressure did not affect the above reaction, benzene and thiazole sulfur ratio of 1: 1.3 when reacted at 240 ℃ 203min, for the M yield was about 91.4%. M is recovered from the accelerator obtained benzothiazole, content of about 78.4%, the remainder component of 14.6% aniline, thio pyromellitic diurea 3.8%, water 3.2%. The mixture was added to CS2 and S, at 250 ℃ tire accelerator M (MBT), 7.59MPa (gauge) at the reaction, the resulting product is accelerator M 85.53%, benzothiazole 5.16%, 0.29% of aniline, sulfur Generation pyromellitic diurea 0.24% aminothiophenol was 0.31% (wt).
