Colorless Liquid 2-Methyl-1-propanol For Rubber Organic Solvent CAS 78-83-1

What is Colorless liquid 2-Methyl-1-propanol For rubber organic solvent CAS 78-83-1?

2-Methyl-1-propanol (CAS No. 78-83-1), an important branched saturated monohydric alcohol with the molecular structure (CH₃)₂CHCH₂OH, exhibits dual properties from its polar hydroxyl group and hydrophobic alkyl chain.

This colorless, transparent liquid has a characteristic odor, a melting point of 108℃, a boiling point of 107.9℃, and a density of 0.806 g/cm³ at 20℃. It is fully miscible with organic solvents such as ethanol, ether, and acetone but remains insoluble in petroleum hydrocarbons, reflecting its amphiphilic nature.

In plasticizer production, 2-methyl-1-propanol reacts with phthalic anhydride to yield diisobutyl phthalate (DIBP), a key additive in polyvinyl chloride (PVC) and rubber processing that enhances material flexibility.
DIBP also serves as a plasticizer for phenolic resins, improving their mechanical properties and durability. As solvents and extractants, 2-methyl-1-propanol functions as an effective medium for coatings, inks, and pesticides, ensuring uniform dispersion of active ingredients. Its selective solvation properties make it a preferred extractant for rare earth elements and precious metals, particularly in the separation of salts like potassium perchlorate and sodium chloride, where its solubility characteristics are critical.

2-Methyl-1-propanol has low acute toxicity, and higher concentrations of vapor are irritating to the eyes, skin, mucous membranes and upper respiratory tract. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The warehouse temperature should not exceed 30℃. Keep the container sealed.
