Chemical Properties

Clear slightly yellow liquid or low melting solid

Originator

Citodorm,Haury

Uses

3-Methylpent-1-yn-3-ol is an inhibitor; used in method for preparing high-insulation solvent-free silicone resin for composite insulator.

Uses

Stabilizer in chlorinated solvents, viscousreducer, electroplating brightener, intermediate insyntheses of hypnotics and isoprenoid chemicals,solvent for polyamide resins, acid inhibitor, preven-tion of hydrogen embrittlement, medicine (soporificand anesthetic).

Definition

ChEBI: Methylpentynol is a ynone.

Manufacturing Process

To 5 parts of sodium acetylene in absolute ether 6 parts of dry methyl ethyl ketone was slowly dropwise added with ice cooling and stirring. Than the reaction mixture was poured into excess of acetic acid by ice cooling and extracted with ether. The ether extract was washed with solution of potash for removing the diluted acetic acid and dried over potassium carbonate. The ether was distilled off and residual colorless oil methylpentynol had BP at 120°-121°C. Instead of sodium acetylene the solution of sodium acetylene in liquid ammonia may be successfully used.

brand name

Dormison (Schering).

Therapeutic Function

Sedative

Hazard

Moderate fire risk. Toxic.
