In order to reduce the waste water and increase the conversion rate of products, domestic scientific research institutions and production enterprises used domestic technology for reference, improved the existing rubber accelerator M process, and achieved results. Domestic researchers have developed a similar solvent extraction process with foreign countries, but there are also problems. Environmental protection, safety and high efficiency selection of new organic solvents is the key to the M per solvendo modum {{II}} quod existentium solvendo extractionem modos includit solventum crystallization modum, distillatoria-extraction modum, solidum-liquido extraction modum, liquido, liquido extractionem modum et sic {{VI}}
In praesens, organicum solvents potest eligere toluene, ipsum disulfide, Aniline, benzene et sic in .
Using Carbon disulfide ut solvendo, sumptus imperium et salutem imperium sunt prominentibus problems .} etsi qualis est firmum et products potest obviam ex internationalis et in salutem necessitates in melius, {I}}
Cum ANILINIUM adhibetur ut solvendo, aniline est leviter solutum in aqua, unde in augmentum in moles aniline in solutione, quae non conducit ad productionem {.
Benzene and toluene are used as solvents, the solubility of the resin is small, the purity of product M is affected, and the recovery of solvent is also considered. Moreover, benzene and toluene are flammable and explosive, the safety factor is low, and volatilization causes solvent loss in the air. Lead to the increase of production costs, but also cause harm to the atmospheric , {{II}}, environment
