Synthetic Route of 6149-41-3, Adding some certain compound to certain chemical reactions, such as: 6149-41-3, name is Methyl 3-hydroxypropanoate,molecular formula is C4H8O3, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6149-41-3.
EXAMPLE 18 20 grams of Cu(NO3)2.3H2O was dissolved in 40 ml of distilled water, and precipitated at PH=8 with 10% by weight of sodium hydroxide to obtain liquid A. 26.0 grams of Na2SiO3.9H2O and 2.3 ml of ethanol solution containing 30% of TiCl4 were dissolved in 60 ml of distilled water, and then precipitated at PH=8 with 10% by weight of sodium hydroxide to obtain liquid B. The liquid A and liquid B were mixed, aged at 80 C. for 4 hours, filtrated, and washed until the filtrate became neutral, dried at 120 C. for 16 hours, baked at 600 C. for 4 hours, and crushed into fine particles, and screened. The particles with a particle size of 20-40 mesh were selected for future use. 1.0 gram of CuCl was prepared into 20 ml of solution, and the above catalyst particles were immersed into the solution for 8 hours, and baked at 350 C. for 4 hours. The catalysts prepared by the above three methods were charged into fixed reactors each having an inner diameter of 15 mm and a length of 250 mm, respectively. The charging amount of the catalyst was 4 grams. H2 was firstly introduced into the reactor, and then the temperature was increased to 300 C. with a increasing speed of 0.5 C./min. The resultant was reduced in situ for 4 hours, followed by decreasing the temperature to 140 C. A methanol solution containing methyl 3-hydroxyl-propionate was introduced into the reactor to carry out a hydrogenation reaction and the results are shown in table 1.
