Abstract

Debituminization of high-moor peat by organic solvents using various extraction methods was studied; the composition of extracted compounds was described. It was proved preferable to use acetate and diethyl ether for debituminization of peat, which is the first step in determining the component composition of peat from a number of solvents (ethanol, hexane, diethyl ether, ethyl acetate). It was found that during the extraction of sub-Arctic peat by organic solvents we obtain raw peat wax with parameters typical for products after a multistage purification.

Keywords

peat, debituminization, extractives, extraction, peat wax.
