New series to be developed chemical intermediates
Body,[link widoczny dla zalogowanych], can be used for a mixture of hydrocarbons and acid dissolved in 2002 as a flame retardant silicone rubber system, in addition to agents, cobalt acetate, manganese acetate, Zhang Yonghua (4), herbicide safeners, conductivity bromide as a catalyst, aerobic Zhang Min Il ~ l3 silicone rubber antioxidant, thermal variable air oxidation of toluene 2,[link widoczny dla zalogowanych],4-Dichloro-color material of a color extension agent. Preparation of (1) to determine the reaction (Beijing l0o037) it with the reaction of ethyl guanidine temperature and pressure. Yield of pyridine compounds can do nerve to 90.8%, the purity of the original protective agent can be achieved, and pyridine, ethyl 99I3%. Pyridine, pyrazine ring to form the ester amide alkyl alcohol is a good sterilizing agent mycophenolate, and substituted pyridine or substituted benzyl alcohol to form esters is an excellent herbicide,[link widoczny dla zalogowanych], and dichlorobenzene reaction to form ionic bonds with high Molecular insulation materials. Between N, N dialkyl amino-benzene (1) is to create thermal (or the method by resorcinol by the Department of Chemistry Petrochemicals phenol (I) Z147 sensitive) dyes intermediates. Through amino and N-alkyl carbon Chemistry and Chemical Engineering 2002, a two-step reaction (1). State Key Laboratory (4) the yield of two-step reaction was l4 ~ 1680%. Li Chunbo advantage of this method can be introduced at the N atom Zhai Kun Xia two different alkyl substituents. Pan Weixiong discussed resorcinol Hsien-Ching Chiu and reactant ratio of n-butylamine (1) the yield and properties. (Beijing lOo084) Chemical�� ��l 2002 to 17-bit uncle - uncle strong _ �� �� delete oath laurate ester of vitamin C (1) of the World Health Organization, the method is based on lauric oil a fine of Dalian Institute of Light Industry Chemicals (1) Z148 Federation recognized food additives and vitamin C ester of Chemical Engineering, 2002, the original can be an efficient, safe, expected to immobilized fats (4) non-toxic, soluble nutrients ester type enzyme as catalyst Xiao-Li Dong 2l ~ 22 were synthesized antioxidant, which is often used to (1). Due to a large variety of study instead of the traditional antioxidant Anqing with the impact of factors on the synthesis reaction in food, pharmaceutical and cosmetics ring, was synthesized (1) (Dalian 116034, China) in. The better the conditions in the optimal reaction conditions, the product can reach a yield of 61.8. Dihydro terpineol (1) Z149 (1) with a lilac scent, which was studied by borohydride Tianjin University Petrochemicals fragrance lasting, and the structure of potassium rather Raney nickel modified carbon chemical key state Laboratory 2002, stability is a good tune catalyst terpineol plus (4),[link widoczny dla zalogowanych], and raw ingredients, prepared in the soap and hydrogen (1) the reaction pressure of 23 ~ 26 Huang Tsung-cool flavor hard synthetic detergent, temperature and stirring That level could reach 20%. Meanwhile, the rate of other factors to determine the most it is double the production of anthracene quinone good technical parameters, (1) (Tianjin 300072) oxygen of water a good solvent, with 98% selectivity to water immiscible, and the flavor off , the yield was 97.69% bacterial Jianzhong Chemical Corporation perfumery. In recent years, more than the spinning. Weaving, paper making industry to gradually switch to hydrogen peroxide bleaching process was Liliang Long Lin for a long time for the bleaching agent to promote hydrogen peroxide (Yibin 644000) consumption rate of 15% a year growth, and hence the market demand for dihydro terpineol increasing. Ethyl acetate (1) Zl50 (1) is the industrial application of the process of introducing the non-alcohol Qiqihar University, Institute of Chemical Petrochemicals often a wide range of solvents can be used and the preparation for the 2002 by-product of acrylonitrile rubber chemicals, paints dilution of acetonitrile was prepared by Xu Qun (4) agent. One-step synthesis of (1) Safety Red 27 to 28 by the orthogonal experiment to determine the best process conditions. In this homogeneous chemical industry limited liability company under the conditions (1) ZHOU Yumei reached 88,8% yield, purity 99.5%. (Qiqihar 161006) on hydroxybenzoate (1), also known Nipagin ester, sodium hydrogen sulfate (2) Education for the catalytic region of Guangxi Nanning Chemical Industry (1) Zl5l good to prevent fermentation, chemical agents, in the microwave field, Department of Chemistry, 2002, inhibit bacterial growth and rapid synthesis of bactericidal against hydroxy (2) the role of the pharmaceutical, food, butyl formate. With a uniform set Lifang Liang l3 ~ l5 cosmetics, film and high yield method to calculate the esterification products obtained preservatives, fungicides. Optimal conditions,[link widoczny dla zalogowanych], and (2) (Guangxi Nanning 530001) reuse and recycling issues were studied. Yield of 96.29%. To (2) as the catalyst of cheap, easily obtained, easily isolated, recovery, recycling and product quality, esterification rate, no pollution, erosion and other small features, is a good catalyst. .
