Synthesis edit Methacrylate production methods are: Acrylonitrile hydrolysis method, the direct oxidation of propylene and ethylene-one method. 1. Acrylonitrile hydrolysis acrylonitrile as a raw material, subjected to hydrolysis in the presence of concentrated sulfuric acid, after hydrolysis of acrylamide sulfate and then with methanol to afford the methyl acrylate. By hydration of acrylonitrile production of methacrylate methacrylate quotes, product consumption per ton of acrylonitrile (98%) 860kg, methanol (95%) 960kg, sulfuric acid (93%) 2000kg. [1] 2. The direct oxidation of propylene to propylene as the raw material, the first step in the oxidation of acrolein, and then oxidized to acrylic acid. Acrylic regenerate methacrylate reaction with methanol. By direct oxidation of propylene production methacrylate, propylene consumption per ton of product (95%) 544kg. 3. ketene Fayi ketene with formaldehyde to boron trifluoride as a catalyst for condensation, quenched with methanol, and methyl acrylate esterification. Integrated application (1) according to the law of conservation of mass: before and after the chemical reaction is equal to the type and number of elements, infer reactants or products of the chemical formula. (2) a known mass of a reactant or product, according to the chemical equation mass ratio of each substance in factory outlets methacrylate, product quality can be obtained or reactants. Application Examples (1) According to the mass conservation law, the sum of the mass of each substance to participate in a chemical reaction generated after the reaction is equal to the sum of the mass of each substance. Using this law can explain the change in the mass before and after the reaction to determine the mass of a substance and the reactants or products with poor quality. (2) According to the mass conservation law, before and after the chemical reaction of the same type and quality of the elements methacrylate, it can be inferred constituent elements of the reactants or products. 4. The quality of the test center and the comprehensive application of the law of conservation of chemical equations (within multidisciplinary test sites) (1) according to the law of conservation of mass: the types and number of atoms in chemical reactions of elements equal to around-the-shelf methacrylate, infer reactants or products of chemical formula. (2) a known reactant or product quality, according to the chemical equation mass ratio of each substance, product quality can be obtained or reactants.
