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.
Claims20
A solvent composition, comprising:
- 91.0 wt.-% or more i-paraffins, the solvent composition having a boiling point in a range of 150° C. to 260° C., wherein the solvent composition is a derivation of a renewable raw material.
A method of applying a solvent composition, the solvent composition having 91.0 wt.-% or more i-paraffins, and a boiling point in a range of 150° C. to 260° C., wherein the solvent composition is a derivation of a renewable raw material, the method comprising:
- applying the solvent composition as at least one of a solvent in coating, paint, lacquer, varnish, polish, ink, adhesive, sealant, resin, plastic, cleaning composition, pigment dispersion, antioxidant, biocide, insecticide, air freshener, crop protection composition, detergent, grease removal composition, dry cleaning composition, cosmetic, personal care composition, pharmaceutical, dental impression material, vaccine, food ingredient, flavour composition, fragrance, natural oil extraction, oil field chemical, drilling mud composition, extraction process composition, plasticizer for elastomer, paper processing chemical, lubricant, functional fluid, transformer oil, metal working composition, rolling or cutting fluid, water treatment composition, wood treatment composition, construction chemical, mould release material, explosive, mining chemical, or a combination thereof.
A method for producing a solvent composition having 91.0 wt.-% or more i-paraffins, and a boiling point in a range of 150° C. to 260° C., wherein the solvent composition is a derivation of a renewable raw material, the method comprising:
- (i) providing a renewable raw material;
- (ii) at least one of hydrotreating or isomerising the renewable raw material to provide a 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 260° 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.
