The Research Institute Of Medicine And Chemical Industry is a central department of the Shaanxi Research Design Institute of Petroleum and Chemical Industry. It is studied on Pharmaceutical Chemistry and Organic Synthesis. We also produce high purity material and fine chemical product. The followings were exploited: the efficient way to synthesize 2-Ethyl-3-hydroxy-4[N]-Pyran-4-one, a food flavors enhancer. A feed additive Olaquindox that obtained the gold medal of National Spark Light Plan was completed. The silver gold of Beijing spark light plan was given us for the N,N-Dimethylaniline. The main product optical whitening agent was titled "the National new product"and "High Technical new product". Shaanxi Research Design Institute of Petroleum and Chemical Industry was founded in 1958.it's belong to shaanxi provincial and we obtained the ISO9001-2000 certificate. it located in the south of the xi'an ,a famous historical city, covering an area of 100000 square meters. Now the enterprise owns over 20 million Yuan fixed assets. It has more than 50000 square meters buildings and more than 400 existing staffs 230 of which are technician, 60 of which are senior engineer and 90 of which are engineer. Shaanxi Chemical Quality Of Product Supervision And Inspect Office, Shaanxi Environmental Protection Monitoring Station Of Petrochemical Product, Shaanxi Chemicals For Water Treatment Assignments Center And Shaanxi Petrochemical Info Center are all stand here. The journal of Applied Chemical Industry is edited here also.
