Chemical properties
Phthalates can be hydrolysis, alcohol and aminolysis reactions, and the reaction with aromatic hydrocarbons can be synthesized into argon derivatives. Phthalates are industrially produced by gas-phase oxidation of niobium and air at 350 to 360 degrees C under the catalytic conditioning of pentoxide, and can also be produced by air oxidation of phthalates. Phthalates can be used instead of phthalates, mainly in response to aluphetamine to form esters, such as phthalates, phthalates. |
