The thermal oxidation stability of ester oils

The oxidation and thermal stability of ester oils are determined by the following factors:

The presence of hydrogen atoms on β -carbon

Polyol esters have excellent thermal stability due to the lack of hydrogen atoms on the β carbon.

The length and structure of the chain

Straight chains are more stable than branched chains.

Short chains are more stable than long chains.

The influence of the three-dimensional structure of alcohols：(PE>diPE>TMP>NPG)

Aromatization：Aromatic hydrocarbon molecules are very stable to oxygen
