Method for preparing fatty acid ester of sorbitan, and a method for preparing a sorbitan Ester alkoxylates from same.

摘要

Sorbide, a fatty acid, is produced by the direct reaction of fat with oxyphosphor (containing oxyphosphor, including reduced phosphoric acid, especially phosphate), sist EMA catalyst and base metal or base metal (especially oxidation), In the grinding acid ratio, the reference value is 0.9:1-1.7:1, and the catalyst concentration is 1.5-30%, especially 3-112%,Without the use of activated carbon and cleaning of commonly used products, the color of absorbent weight may be lower than that of commercially known mass processed products. These esters can be derived from tar dioxide, especially polyurethane. Polyvinyl chloride esters and derivatives are measuring tools that can be used for various purposes. Low color products made without carbide or without washing or activity are attractive for personal care purposes.
