stannous
2.Butyraldehyde 1,2 proparediol acetal was synthesized by using stannous chloride as catalyst.
3.A NEW METHOD FOR PREPARATION OF 99 mTc-LABELED STANNOUS PHYTATE AND COMPOUND′S CLINICAL APPLICATION
4.then add catalyst with 1% weight of reactant, (stannous octanoate with 1% volume of reactant);
5.JCIG Lianhua Welfare Chemical Industry Factory - Specialized producer of triethyl phosphate, methyl phosphate, methyl dichloroacetate, stannous oxide, and palladium chloride.
6.Modified polylactic acid is synthesized from lactide and aminophenol by morpholine-dione with stannous octoate as the crystal.
7.These complexes react with hydrogen chloride, acetyl chloride and thionyl chloride to form the parent dichloride (η~5-RC_5H_4)_2 MCl_2. and with stannous chloride to form Mo—Sn bonding complexes.
8.Polylactic acid (PLA) of different molecular weights were synthesized by the direct condensation of lactic acid with modified gneiss as the catalyst, or with modified gneiss and stannous caprylate as the catalyst in the same reaction conditions and different reaction times.
9.Esterification was conducted at 0.097 MPa,200 ℃ for 6 h with n(DFA)/n(PEG 400)=1.2,stannous chloride was the preferable catalyst and the amount used was 0.3% of total amount of reactants.
10.The optimum reaction conditions of esterification were as follows: molar ratio of DFA /PEG 400 1 ∶1.20,stannous chloride as the preferable catalyst at amount(0.30?%) of DFA,reaction temperature(200?℃),reaction time 6 h,the conversion can reach(98.11?%).
