Abstract
A renewable solvent composition having a high i-paraffin content of at least 91.0 wt.-% and a boiling in a range of from 150° C. to 260° C. is disclosed. The solvent composition can provide a good balance between solvency power and cold properties and is usable in a broad application field.
Claims18
A solvent composition, comprising:
- paraffins,
- wherein the paraffins include C5 to C15 paraffins and i-paraffins;
- wherein a content of the C5 to C15 paraffins is 95 wt.-% or more,
- wherein a content of the i-paraffins is 91.0 wt.-% or more, relative to the solvent composition as a whole;
- wherein there is more than 55.0 wt.-% dimethylated, trimethylated or higher methylated i-paraffins relative to all of the i-paraffins in the solvent composition;
- and wherein:
- the solvent composition is a derivation of a renewable raw material including at least one or more of:
- a fat or an oil of any plant origin, of any animal origin, or of any microbial origin, including algae and fungi, fish, vegetable oil/fat, animal oil/fat, food industry waste oil/fat, algae oil/fat, microbial oil, palm oil, rapeseed oil, algae oil, jatropha oil, soybean oil, cooking oil, vegetable oil, animal fat or fish fat;
- and
- the solvent composition having a boiling point in a range of 150° C. to 250° C. and an aniline point of 83° C. or below via hydrotreating the renewable raw material to form hydrotreated material, isomerising the hydrotreated material obtained in the hydrotreating of the renewable raw material to provide an isomeric raw material, and distilling the isomeric raw material to form the solvent composition.
A method for producing a solvent composition having 91.0 wt.-% or more i-paraffins, a boiling point in a range of 150° C. to 250° C., and a low content of low-carbon number C5 to C10 n-paraffins relative to the solvent composition as a whole, wherein the solvent composition is a derivation of a renewable raw material, the method comprising:
- (i) providing a renewable raw material, the renewable raw material including at least one or more of:
- a fat or an oil of any plant origin, of any animal origin, or of any microbial origin, including algae and fungi, fish, vegetable oil/fat, animal oil/fat, food industry waste oil/fat, algae oil/fat, microbial oil, palm oil, rapeseed oil, algae oil, jatropha oil, soybean oil, cooking oil, vegetable oil, animal fat or fish fat;
- (ii) hydrotreating the renewable raw material to form hydrotreated material and isomerising the hydrotreated material obtained in the hydrotreating of the renewable raw material to provide an isomeric raw material;
- and
- (iii) distilling the isomeric raw material, thereby obtaining a fraction boiling in at least one of a range of 150° C. to 250° C., a range of 160° C. to 250° C., or a range of 170° C. to 240° C., which is recovered as the solvent composition, optionally after further purification;
- wherein the solvent composition comprises
- paraffins, the paraffins including C5 to C15 paraffins and i-paraffins;
- wherein a content of the C5 to C15 paraffins is 95 wt.-% or more and a content of the i-paraffins is 91.0 wt.-% or more relative to the solvent composition as a whole;
- wherein there is more than 55.0 wt.-% dimethylated, trimethylated or higher methylated i-paraffins relative to all of the i-paraffins in the solvent composition and the solvent composition has an aniline point of 83° C. or below.
