Rubber accelerator cleaning process to obtain new breakthroughs

Constraints of the global rubber accelerator industry for decades-old 'three wastes' problem is expected to make a breakthrough. Reporters learned that from the Tianjin Comay Chemical Co., Ltd. last week, by its commitment to the promotion of M clean production process development and high levels of rubber antioxidant the TMQ (RD), two projects have been identified by experts.

Among them ,the rubber accelerator M clean production process has now entered the pilot phase and  in 2012 will be realized industrialization,and the effective content of the high content rubber antioxidant will be more than80%. In recent years, the production and demand of domestic and international rubber accelerator M is increasing year by year, but its development prospect is concerned. Because the present global accelerator production enterprise widespread use of the method of aniline production technology, product yield, there has been a low, refining process raw material cost is high, the pollution of the environment defects, and the current global low carbon, environmental protection industry development requirements are antipathetic.

Xu Chunhua, chairman of the rubber chemicals Professional Committee of China Rubber Industry Association, believes that the newly developed rubber accelerator M cleaner production processes is expected to exceed the rubber to promote the product prepared by the agent 'wastes' emissions problems, ,the project on high levels of the TMQ Rubber Antioxidant (RD) has reached international advanced level of similar products.Accelerator M cleaner production technology development projects through the synthesis of aniline reaction accelerator M in-depth study to determine the mechanism of the reaction of accelerator M, the theoretical basis of the synthesis reaction.  the Researchers completed the ratio of reactants, reaction temperature, reaction time and the optimization of the operation control program and other major reaction conditions, the world's first development of CS2 high temperature extraction and crystallization accelerator M sets of cleaner production processes was developed successfully.

The production process close to the 'three wastes' zero emissions, and accelerator M product reached yield of 94% or more, 10% higher than the original technology, has the remarkable social benefit, economic benefit and ecological benefits.. Rubber antioxidant of high content of the TMQ (RD) project has developed a solid acid catalyst synthesis technology, the conversion rate of the reaction, high selectivity, low reaction temperature, the catalyst can be reused. The project successfully developed Tianjin the Comay first produce the rubber antioxidant TMQ(RD), the effective content of greater than 80% of the enterprise. Function-oriented crystalline materials through the acceptance of security of the company to yield a saving of coal seam gas content and pressure measuring device to the advent of large grain quasi-monocrystalline silicon ingot in the East China Sea to test the acid-base waste processing equipment patented PPG introduced biodegradable scrubber the green substrate.
