POLY ALKANOL ESTERS OF ALKYLTHIO-ALKANOIC ACIDS

POLY ALKANOL ESTERS OF ALKYLTHIO-ALKANOIC ACIDS

Alkyl esters derived from alkylthioalkanoic acids and alkane polyols are stabilizers of organic material normally subject to thermal and oxidative deterioration. They are prepared by conventional esterification techniques. Typical embodiments are pentearythritol tetrakis (3-n-dodecylthiopropionate)...

Beschreibung
Zusammenfassung:Alkyl esters derived from alkylthioalkanoic acids and alkane polyols are stabilizers of organic material normally subject to thermal and oxidative deterioration. They are prepared by conventional esterification techniques. Typical embodiments are pentearythritol tetrakis (3-n-dodecylthiopropionate) and ethylene bis (3-n-didecylthiopropionate). The esters are used in conjunction with phenolic antioxidants to effectively stabilize organic materials from the deliterious effects of heat and oxygen.
