Applications N-substituted allyl and N-substituted propargyl amines are prepared by bismuth methyl carbamate-catalyzed substitution of allyl or propargyl alcohols. Chemical properties White crystals. It is easily soluble in water, but also in organic solvents such as ethanol and acetone. Uses As intermediates in medicine, pesticides and organic synthesis Uses As intermediates in organic synthesis in pharmaceuticals, pesticides and other industries, as a selective solvent for aromatic hydrocarbons, this product of molten Chemicalbook is also used as a solvent for various insoluble organics and resins solvent. Synthesis of dimethyl carbonate with methanol. The production method is derived from the reaction of urea and methanol. The methanol was heated to a slight boil, and urea was added in portions under stirring, and the mixture was refluxed for 30h after the addition. After the excess methanol is recovered, the extract is boiled and extracted twice with petroleum ether for fractionation, and the fraction at 175-177° C. is collected as methyl carbamate. The yield was 75%.
