有机化学中各种物质的转换（The conversion of various substances in Organic Chemistry）

有机化学中各种物质的转换（The conversion of various substances in Organic Chemistry） Methane combustion CH4+2O2 - CO2+2H2O (condition for lighting) Methane is isolated from air by high temperature decomposition The decomposition of methane is very complex, and the following is the final decomposition. CH4 - C+2H2 (condition of high temperature, high pressure, catalyst) Methane and chlorine undergo substitution reactions CH4+Cl2 to CH3Cl+HCl CH3Cl+Cl2 to CH2Cl2+HCl CH2Cl2+Cl2 to CHCl3+HCl CHCl3+Cl2 = CCl4+HCl (conditions are light) Laboratory methane production CH3COONa+NaOH - Na2CO3+CH4 (condition CaO heating) Ethylene combustion CH2=CH2+3O2 - 2CO2+2H2O (condition for lighting) Ethylene and bromine CH2=CH2+Br2 to CH2Br-CH2Br Ethylene and water CH2=CH2+H20 - CH3CH2OH (condition as catalyst) Ethylene and hydrogen chloride CH2=CH2+HCl to CH3-CH2Cl Ethylene and hydrogen CH2=CH2+H2 - CH3-CH3 (condition as catalyst) Ethylene polymerization NCH2=CH2 - -[-CH2-CH2-]n- (condition as catalyst) Vinyl chloride polymerization NCH2=CHCl - -[-CH2-CHCl-]n- (condition as catalyst) Laboratory production of ethylene CH3CH2OH, CH2=CH2 = +H2O (conditions for heating, concentrated H2SO4) Acetylene combustion C2H2+3O2 - 2CO2+H2O (condition for lighting) Acetylene and bromine C2H2+2Br2 to C2H2Br4 Acetylene and hydrogen chloride Two step reaction: C2H2+HCl = C2H3Cl--------C2H3Cl+HCl = C2H4Cl2 Acetylene and hydrogen Two step reaction: C2H2+H2 to C2H4 = C2H2+2H2 to C2H6 (condition as catalyst) Laboratory acetylene CaC2+2H2O, Ca (OH) = 2+C2H2 Equation for synthesizing polyethylene with salt, water, limestone and coke as raw materials. CaCO3 = CaO + CO2 2CaO+5C===2CaC2+CO2 CaC2+2H2O = C2H2+Ca (OH) 2 C+H2O===CO+H2----- high temperature C2H2+H2 - C2H4 - acetylene addition yields ethylene C2H4 polymerizable Benzene combustion 2C6H6+15O2 - 12CO2+6H2O (condition for lighting) Substituted benzene and bromine. C6H6+Br2 to C6H5Br+HBr Concentrated nitric acid C6H6+HNO3 - C6H5NO2+H2O (condition is concentrated sulfuri
