    摘要: Disclosed is a process for the preparation of 11-(4-[2-(2-hydroxyethoxy)ethyl]-1-piperazinyl)-dibenzo[b,f][1,4]thiazepine. In the process, low-priced 2,2′-dithiosalicylic acid as starting material is subjected to bond formation reaction with 1-chloro-2-nitrobenzene in a basic aqueous solution, a nitro group reduction reaction is conducted, cyclization and chlorination reactions are simultaneously carried out in the presence of a equivalent amount of halogenating agent, a reaction with piperazine is continuously conducted without separation, and a reaction with 2-haloethoxyethanol is conducted, thereby it is possible to economically producing Quetiapine, that is, 11-(4-[2-(2-hydroxyethoxy)ethyl]-1-piperazinyl)-dibenzo[b,f][1,4]thiazepine, in an environmentally friendly manner. Particularly, the process is advantageous in that economic efficiency is assured because of use of the low-priced starting material, use of an organic solvent is minimized because a reaction is conducted in an aqueous solution, and it is possible to achieve the environmentally friendly and economical process having high commercial usefulness because the number of reaction steps of the process is reduced and because generation of acidic waste is minimized.

    摘要: Disclosed is a process for producing light olefins from hydrocarbon feedstock. The process is characterized in that a porous molecular sieve catalyst consisting of a product obtained by evaporating water from a raw material mixture comprising a molecular sieve with a framework of Si—OH—Al— groups, a water-insoluble metal salt, and a phosphate compound, is used to produce light olefins, particularly ethylene and propylene, from hydrocarbon, while maintaining excellent selectivity to light olefins. According to the process, by the use of a specific catalyst with hydrothermal stability, light olefins can be selectively produced in high yield with high selectivity from hydrocarbon feedstock, particularly full-range naphtha. In particular, the process can maintain higher cracking activity than the reaction temperature required in the prior thermal cracking process for the production of light olefins, and thus, can produce light olefins with high selectivity and conversion from hydrocarbon feedstock.
