Pentaerythritol

Pentaerythritol

CAS No: 115-77-5
Formula: C5H12O4

Pentaerythritol is a white crystalline solid.Odorless.pentaerythritol: white crystallinecompound, C(CH2OH)4; m.p.260°C; b.p. 276°C (30 mmHg). It isused in making the explosive pentaerythritoltrinitrate and in producingresins and other organicproducts.Odorless white solid. Sinks and mixes slowly with water.
Discription: Mainly used in the production of alkyd resins, as well as raw materials for the manufacture of inks, lubricants, plasticizers, surfactants, explosives and drugs; used as antistatic agents for resins and synthetic fibers, solvent conditioners, fiber oils, etc. ; Pentaerythritol is mainly used in the coating industry. It is a raw material for alkyd resin coatings. It can improve the hardness, gloss and durability of the coating film. It is also used as a raw material for rosin resin required for varnishes, paints and printing inks. , And can make smoldering paints, drying oils and Fangkong lubricants. The tetranitrate of pentaerythritol is a kind of high explosive (namely Tai’an); its fatty acid ester is a high-efficiency lubricant and polyvinyl chloride plasticizer; its epoxy derivative is the raw material for the production of non-isolated surfactants, pentaerythritol It is easy to form an authoritative complex with metals, and can also be used as a hard water softener in detergent formulations. In addition, it should also be used in the production of medicines and pesticides. Used in the coating industry, can also be used to prepare aviation lubricants, explosives, plasticizers, stabilizers; used as gas chromatography reagents and pesticides
