Synthesis of pentaerythritol diacetals and diketals catalyzed by methanesulfonic acid;

Synthesis of star-shaped poly(p-dioxanone) by pentaerythritol;

Effect of 4A Zeolite on Property of Flame Retardant PP by Melamine Phosphate/Pentaerythritol;

The factors such as pH value,pressure and time in pressurized hydrolysis of pentaerythrite solution and pentaerythrite mother liquor are studied.

Bis(bromomethyl) 1,3 propanediol as a good reaction type fire retardant was synthesized by some processes such as replacement reaction, decompression separation, purification and drying from pentaerythrite and 40% hydrobromic acid solution in catalysis of glacial acetic acid, with a yield of 80.

Synthesis and Application of Dipentaerythritol Ester;

Synthesis of lubricating oil dipentaerythritol hexa-esters under microwave radiation;

Synthesis of dipentaerythritol hexaacrylate;

A process for the preparation of mono-pentaerythritol by condensation of formaldehyde and acetaldehyde with sodium hydrate as base was studied,and effect of reaction temperature and time,concentration of formaldehyde and acetaldehyde,and molar ratio of reactants was investigated.

As a result, contents of mono-pentaerythritol, di-pentaerythritol and ash are significantly decreased in the finished tripentaerythritol, where mono-pentaerythritol content changes form 7% to 3%, di-pentaerythritol content changes from 18.
