Tert-Butyl Peroxy Benzoate Catalysis
TBPB is a low volatility ,high purity,liquid, aromatic peroxuester.it is effective as medium of a broad spectrum of monomers e.g .styrene.ethylenn,acrylics.it is also used to cure (copolymerzation) unsaturated resins .
As peroxo compound, TBPB contains about 8.16 wt% of active oxygen and has a self accelerating decomposition temperature (SADT) of about 60 °C. The SADT is the lowest temperature at which self-accelerating decomposition in the transport packaging can occur within a week, and which should not be exceeded while storage or transportation.[2] TBPB should therefore be stored between minimum 10 °C (below solidification) and maximum 50 °C. Dilution with a high-boiling solvent increases the SADT. The half-life of TBPB, in which 50% of the peroxy ester is decomposed, is 10 hours at 104 °C, one hour at 124 °C and one minute at 165 °C. Amines, metal ions, strong acids and bases, as well as strong reducing and oxidizing agents accelerate the decomposition of TBPB even in low concentrations.[ However, TBPB is one of the safest peresters or organic peroxides in handling. The main decomposition products of tert-butyl peroxybenzoate are carbon dioxide, acetone, methane, tert-butanol, benzoic acid and benzene.

At the meeting, the engineers of the grain dryer production enterprise were invited to explain the structure, use and maintenance of the dryer from a safety perspective; the agricultural machinery policy insurance underwriting company explained the new trial grain food insurance clause in detail. The owners who participated in the training said that the safety training is very applicable and practical, and it is of great help to the usual management. The food dryer insurance guarantee is also comprehensive.
In order to comprehensively guarantee food security and enhance farmers' ability to resist risks, according to the spirit of "Jiangsu Province Grain Dryer Insurance Clause Rate (Trial)", Yancheng City will pilot the implementation of grain dryer policy insurance in this city this year. The insurance premium owner will undertake Half, half of the financial subsidies. Implementing grain dryer insurance will help farmers to quickly resume agricultural production. It is a benefit-mining measure that responds to farmers' expectations and increases farmers' feelings. At the same time, through the insurance company to guide and supervise the safety management of the insured's drying workplace, and put forward suggestions for eliminating safety hazards, which will help improve the safety supervision ability of agricultural machinery.
Recently, Yancheng City held a training workshop on grain dryers in the Zhiting Lake area, the development zone and the Chengnan New District. Nearly 60 people participated in the training of grain dryer owners and agricultural machinery safety supervisors in the municipal district.
