▶Polypropylene glycol(PPG)

25322-69-4

Polypropylene glycol(CAS:25322-69-4)The systematic name of Polypropylene glycol is Poly(oxy(methyl-1,2-ethanediyl)), alpha-hydro-omega-hydroxy-. With the CAS registry number 25322-69-4, it is also named as Methyloxirane homopolymer. The product's categories are Polymers; Ethers; Hydrophobic Polymers; Propylene Glycol; Poly(propyleneglycol); Alphabetic; Water Soluble Polymers. It is viscous colourless liquid which is soluble in water (low molecular weight ), aliphatic ketons, alcohols and other organic solvents, insoluble in ether and most of the aliphatic hydrocarbons. When use it, people should avoid contact with skin and eyes. Additioanlly, this chemical should be sealed in the container and stored in the cool and dry place. When heated to decomposition it emits acrid smoke and irritating fumes.

▶Neopentyl Glycol（NPG)

126-30-7

A white, odorless crystalline solid with a high melting point (124-130℃) and excellent thermal stability. It has a molecular weight of 104.15, low hygroscopicity, and good chemical inertness. Soluble in water, ethanol, ethylene glycol, and other polar solvents, it is insoluble in non-polar solvents like benzene and hexane.

▶Methanol

67-56-1

Methanol is a colorless, highly volatile liquid with a wine-like odor. It has a molecular weight of 32.04, a boiling point of 64.7℃, and a melting point of -97.8℃. Miscible with water, ethanol, ether, and most organic solvents, it is a polar solvent with strong solubility. Notably, it is highly toxic—ingestion or inhalation of large amounts can cause severe damage to the central nervous system and organs like the liver and kidneys.

▶Isobutanol（IBA)

78-83-1
