1-Butanol is also called butyl alcohol is represent of singleatom alcohols.

Purchase of 1-Butanol will suit for you, if you use one of the next branches of industries:

It goes as a solvent in the paint industry, in resin and plasticizer production

  • modifiers urea and melamine-formaldehyde resins;
  • for plasticizers: dibutyl phthalate, tributyl;
  • for butyl acetate and butyl acrylate esters with glycols;
  • in the synthesis of many organic compounds.

2-methylpropanol-1 (isobutyl alcohol, isobutanol) is an alcohol with the formula (CH3) 2CHCH2OH, colorless, flammable liquid with a characteristic smell. Mainly used as a solvent. Other isomers of butyl alcohol: 1-butanol, 2-butanol, 2-methylpropanol-2.

The industrial production of 2- methylpropanol -1 involves the use of three methods:

 

  • propene hydroformylation ( oxo synthesis );
  • catalytic hydrogenation of carbon monoxide (II);
  • homologation reaction;

 

The first method relies on the reaction of propylene with carbon monoxide and hydrogen in the presence of a cobalt catalyst at a temperature of 100-180 °C and a pressure of 20—30·106 Pa. At the same time as products are simultaneously formed butanal, and 2- methylpropanal, which ratio under these conditions was 3: 1. Modern processes, which use a catalyst based on rhodium modified have greater selectivity, giving 92-95 % butanal. At the same time, the use of unmodified rhodium leads to a substance of 50 % 2- methylpropanal in the final product mixture. Further hydrogenation of 2- isobutyl alcohol gives methylpropanal.

2-Methyl-2-propanol (tert-butyl alcohol, tert-butanol, trimethyl, 1,1-dimethylethanol), it's a representative of tertiary monoalcohols.

It's obtained from reaction of isobutylene with sulfuric acid, followed by hydrolysis. Its appearance consists of fusible colorless crystals. Mixed with water, it gives an azeotrope (bp. 79,9 ° C, 11,8% of water). It is soluble in organic solvents.

Purchase of 2-methyl-1-propanol and purchase of 2-methylpropyl alcohol would be easily deal for you on our site. It's used in the production of high purity isobutene. It works as the alkylating agent, a solvent, an antiseptic. As a fragrance in perfumes (camphor smell). Alcohol is used for denaturation.
