The main components of pentaerythritol
◆Introduction:industrial Pentaerythritol products currently there are three main levels, namely 99, 98 and 93, are widely used in the coatings industry, synthetic lubricants, synthetic plasticizers, synthetic surfactants, antioxidants and explosives and medicine.
Description:The company pentaerythritol production process means is imported from Italy EUROTECNICA entire company, using low sodium method continuous production process of advanced production equipment, product quality is superior to the British ICI pentaerythritol standards.
◆ Packaging: in bags (25 kg / bag, 500 kg / bag)
◆Physical properties Molecular formula: C5H12O4, molecular weight: 136.15. Characters: the white crystalline powder, flammable, susceptible to general organic acid esterification, and dilute caustic soda solution and cook no response. Density (g / mL): 1.399 Melting point (ºC): 262, boiling point (ºC): 380.4, refractive index (20ºC): 1.54 ~ 1.56, a flash point (ºC): 102, Flash point (ºC): 370, ignition point or ignition temperature (ºC): 450 (powder), the saturation vapor pressure (kPa, 276ºC): 4.0, heat of combustion (KJ / kg): 2765, lower explosive limit (%, V / V): 30 (g / m3), The relative density (20 ℃, 4 ℃): 1.397. Stability: very stable in the air, not water, other properties: slight sweetness, basic non-toxic.

◆CHEMICAL PROPERTIES Solubility: soluble in water, ethanol, glycerol, ethylene glycol, formamide. Insoluble in acetone, benzene, carbon tetrachloride, ether and petroleum ether. Pentaerythritol, the hydroxyl groups can occur esterification, nitration, halogenation, etherification and oxidation reactions, with the formation of metal complexes.
◆Product transport and storage protection of this product is stored in a cool, ventilated warehouse. Away from fire, heat source. Should be stored separately with oxidants, acids, etc., avoid mixing reservoir. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with suitable material spill. When pentaerythritol dust concentration in the air up to 30g / m3 or more, and can form explosive mixtures with air, when the explosion occurred when over 400 ℃. It should be stored in a cool, dry, well-ventilated place, moisture, fire. As a general chemical storage and transportation.
