Abstract:
A process for the recovery of carotenes and the production of carotene concentrate from natural oils and fats. The carotene-containing natural oils and fats is subjected to alcoholic esterification to form a mixture of fatty acid alkyl esters, carotenes, tocopherols and tocotrienols. The alkyl esters mixture is subjected to vacuum distillation at a pressure of less than 60 mTorr and a temperature of less than 180.degree. C. to form a carotene-rich concentrate. The carotenes in the carotene-rich concentrate are adsorptively separated, concentrated and collected as carotene-rich fraction.
Abstract:
An emulsion composition for use as potentiator in a soluble liquid herbicide formulation comprising a natural oil-based ester, a hydrophilic surfactant, a lipophilic surfactant, a natural oil-based ethanol amide co-surfactant and a natural oil-based glyceride ethoxylate co-surfactant.
Abstract:
A fiberboard comprising dried plant fibers added with binder resins obtained from a reaction between a diisocyanate and a polyol derived from natural oils or fatty acids, and formed by pressing at a temperature range of 50° C. to 150° C.
