4,4'-Bis(pentyloxy)-1,1'-biphenyl

Basic information:

CAS number: 21470-41-7.

Molecular formula: C₂₂H₃₀O₂.

Molecular weight: 326.47.

Chemical structure: Two benzene rings connected by a single bond, and the 4 positions of the two benzene rings are connected to a pentyloxy (-OC₅H₁₁) group.

Physical and chemical properties:

Appearance: Crystal or powder, white to off-white in color.

Solubility: Insoluble in water, soluble in some organic solvents.

Stability: Stable under normal conditions, heating and decomposition will produce complex products, and the specific decomposition products are related to the decomposition conditions.

Use: It can be used as a foaming agent for plastics and rubbers, and used in foam materials for the shoemaking industry, with a dosage of 3% - 6.5%. It can also be used for the foaming of various polymer materials such as polyvinyl chloride, polyester, polyamide, etc., with a dosage of 1% - 15%. Because it releases heat during decomposition, it is generally mixed with sodium bicarbonate.

Safety information: No clear carcinogenicity or reproductive toxicity has been found so far, but as a chemical, it may be irritating to the eyes, skin and respiratory tract, and direct contact should be avoided. In case of leakage, it is recommended to dissolve and mix in a flammable solvent and burn in a chemical incinerator equipped with post-combustion and washing equipment. All national, regional and local regulations must be followed when disposing of the waste.
