Abstract

Fusel oil from methanol prepared from coal comprises the main component of a mixture of various alcohols such as methanol, ethanol, propanol, isopropanol and the like and a small quantity of sulphides, and has awful and pungent odor. An odor remover for fusel oil from methanol prepared from coal has the advantages that the odor removal effect is remarkable, the process is simple, operation is easy, emissions are prevented, the environment is protected, and pollution is avoided; the consumption is low, and the cost is low; the economic benefit and the social benefit are remarkable.

Description

technical field [0001] The invention belongs to the field of chemical production, and in particular relates to a fusel oil odor remover and a preparation method thereof. Background technique [0002] Fusel oil is one of the by-products of alcohol production by fermentation, and it is a general term for a mixture containing various alcohols. Fusel oil is a light yellow oily liquid with special odor and toxicity. The main components of fusel oil are ethanol, n-propanol, n-butanol, isobutanol, sec-butanol, amyl alcohol, isoamyl alcohol, water and a small amount of aldehydes, alcohols, esters, acids, unsaturated More than 20 kinds of ingredients such as terpene compounds, pyridine, and alkaloids. The C2-C5 alcohols contained in fusel oil can all form azeotropes with water, and the constant boiling point difference between each azeotrope is smaller than the boiling point difference between corresponding alcohols, making the separation of each component very difficult. Because ...
