Chemistry is traditionally divided into organic and inorganic chemistry. Product Details of 165253-31-6, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 165253-31-6
A tetrahydrofuran – 3 – methylamine novel synthesis process (by machine translation)
The invention discloses a tetrahydrofuran – 3 – methylamine novel synthesis process, solved in the prior art in a manufacturing process, the raw materials are not only expensive, raising the production cost, but also the production process would release a large amount of heat and flammable and explosive gas hydrogen, will be brought to the production the security risk. The invention comprises (1) in the organic solvent, 2, 5 – dihydrofuran catalyst under the action of the A poly formaldehyde and hydrogen chloride reaction, to obtain the methyl – 2, 5 – dihydrofuran; (2) methyl – 2, 5 – dihydrofuran with hexamine reaction to obtain the amine methyl – 2, 5 – dihydro benzofuran hydrochloride, then using sodium hydroxide solution free leaves the amine methyl – 2, 5 – dihydrofuran, distilled to obtain crude; (3) the crude amine methyl – 2, 5 – dihydrofurans under the effects of catalyst by the hydrogen reduction to obtain 3 – tetrahydrofuran methylamine, filtering, rectifying the filtrate to obtain the pure product. The invention has the low cost of raw materials, little three-waste discharge, simple process and the like. (by machine translation)
