Notice of Retraction The study on conveyor belt materials to heat-resistant performance characteristics

This paper proposes an improved method, the performance and characteristics by doping conveyor belt conveyor belt materials and nanometer materials filled. Overall, it is the use of nano program statement from the traditional technological method of a milestone may establish a belt conveyor system development. Results show that the coating of comparative analysis, TPU based the using nano-materials ran packing lead to substantially smaller friction coefficient and the causes, improved energy consumption. The main target of this project is DotTrans therefore, development of new conveyer belt, and have significantly improved technological characteristics, these nano used by program.

Study on the reaction mechanism of naphthalene with oxalyl chloride

The reaction of naphthalene with oxalyl chloride in the presence of anhydrous AlCl3 was investigated. The homolog of dinaphthyl methanone can be obtained mainly from this reaction. Naphthalene conversion does not have evident correlation with the amount of AlCl3. The results show that the reaction proceeds via carbon cation electrophilic substitution reaction-free radical substitution reaction pathway.

The reaction of acenaphthene with nitrobenzene

The reaction of acenaphthene with nitrobenzene was investigated in the presence of AlCl3. The results showed that the reaction proceeded via carboncation-electrophilic substitution reaction and free radical substitution reaction pathway. The products of acenaphthenyl phenylamine and biacenaphthyl could be synthesized by this reaction. The influence of the amount of AlCl3 and the temperature on the components of products were also studied in this reaction.
