1-propanol

Product name 1-propanol
Synonyms primary propyl alcohol
normal propyl alcohol
GOST no data
CAS 71-23-8

1-Propanol is a clear, colorless liquid with a weak alcohol smell. It is soluble in ethanol, methanol, diethyl ether, benzene. 1-Propanol is miscible in water and forms azeotrope with it (71.7% of 1-propanol by mass, bp 87.5-88.0°C). It is a typical monoatomic alcohol.

Production.

1-Propanol is manufactured in two-stage process by ethylene hydroformylation at 80-120°C and 2.0 MPa in the presence of cobalt or rhodium carbonyl followed by hydrogenation on copper-chromium or nickel-chromium catalyst:

CH2=CH2 + CO --> CH3CH2CHO
CH3CH2CHO + H2 --> CH3CH2CH2OH


Uses.

1-Propanol is used:

  • as a solvent for waxes, polyamides, natural and synthetic resins, polyacrylonitrile, cellulose esters;
  • as a reaction medium in making low density polyethylene (LDPE)
  • as an alkylating agent in organic synthesis;
  • to prepare propionic acid, propionic aldehyde, propyl acetate, propylamine;
  • to manufacture pesticides and surface-active substances;
  • as an intermediate to produce pharmaceuticals;
