Synthesis process and application of dicyclopentadiene maleate;

The synthesis of glyoxylic acid by ozonization of maleate was studied, the influence of technological parameter on the reaction during ozonization process were investigated.

Using maleic anhydride and dodecylpolyoxyethylene ether-15(AEO15)as raw materials,a maleate-based polymerizable emulsifier with structure combining the characteristics of nonionic and anionic surfactants was synthesized by a green route.

Thus,maleic anhydride reacted with fatty alcohols at 90 ℃ for 3 h to produce maleic monoesters.

Maleic diester polymer fatliquor agents(PMF) were synthesized with hydrophilic monomer dodecanol maleic monoester(ME),dodecanol n-butanol maleic diester(DE),hydrophibic monomer methacrylic acid(MAA) and the initiator ammonium persulfate by the free radical water emulsion polymerization,in which more active monomer was supplemented in batches.

Maleic monoester polymer fatliquor agents(PRF)were synthesized with long-chain alcohol maleic monoester(ME)and acrylic acid(AA)by the reaction in which more active monomer AA was supplemented in batches.

The Synthesis of Maleates Catalyzed by Solid Acid under Microwave Irradiation;

In the presence of these ionic liquids as catalyst,the reaction of synthesizing diisooctyl maleate was studied.

A terpolymer of styrene,diisooctyl maleate,octadelyl acrylate was synthesized as pour point depressant for base-oils.
