Neopentyl Glycol Production Technology

Neopentyl glycol, short form NPG, chemical name: 2,2-Dimethyl-1,3-propanediol; molecular formula: C5H12O2molecular weight: 104.15white crystal solidodorlesshas moisture absorption propertymelting point: 124~130℃boiling point: 210℃density:(21℃)1.06g/cm3flashing point: 129℃self-ignition point: 399℃sublimation tem.: 210℃, easily dissolved in water, low grade alcohol, ketone, ether and aromatic compounds etc.

Section A Application of Neopentyl glycol

Application of Neopentyl glycol Mainly used to produce UPR, polyester powder coatings, oil free alkyd resin, foamed PU plastic, elastic plasticizer, synthetic plasticizer, surfactants, insulation materials, printing inks, aero oil product and oil additives. It is also used in pharmaceutical industry. Neopentyl glycol is good solvent, can be used for the separation of aromatic and naphthenic base hydrocarbon separation. See the form below to refer to the application of neopentyl glycol

Section B Production Flow Of Neopentyl Glycol

1.Process line selection
There are two neopentyl glycol production way. One is one-step synthesis way, the other is two-step synthesis way. Two-step synthesis way in domestic China is always in research stage. The enterprise, who adopts two-step synthesis way to produce neopentyl glycol has to stop because of technology problem. The traditional one-step synthesis way is relative simple but formaldehyde is removed too much ,lots of alkine is consumed and lots of waste water is produced. Jiangsu Kaimao Chemical Technology Co., Ltd. has developed new process with competitive advantage, which changes the defect of large waste water amount, high single consumption, high production cost and product agglomerate.

2.Process line

In this process, one-step way synthesis catalyst synthesis of new technology is adopted. Compared to traditional production process, high yield, high purity product, well stability can be be received. Sodium formate is produced in reactant. Neopentyl glycol is extracted with extraction method. In the extraction procedure of one-step improving method, according to the difference of boiling point and solubility in reaction liquid’s each component , conduct dual vacuum decompression evaporation, salt removing through centrifugation, cooling absorption, distillation dehydration, rectification to receive final-product of neopentyl glycol. Adopt this production process to pr
