Procedure

Specific examples of such ester compounds include a carboxylate mixture formed between pentaerythritol and n-pentanoic acid/3,5,5-trimethylhexanoic acid, a carboxylate mixture formed between pentaerythritol and n-pentanoic acid/2-methylbutyric acid/3,5,5-trimethylhexanoic acid, a carboxylate mixture formed between pentaerythritol and n-heptanoic acid/3,5,5-trimethylhexanoic acid, a carboxylate mixture formed between pentaerythritol and n-octanoic acid/3,5,5-trimethylhexanoic acid, a carboxylate mixture formed between pentaerythritol and n-octanoic acid/2-ethylhexanoic acid/3,5,5-trimethylhexanoic acid, trimethylolpropane tri-3,5,5-trimethyl hexanate, a carboxylate mixture formed between pentaerythritol and 2-ethylhexanoic acid/3,5,5-trimethylhexanoic acid, and a carboxylate mixture formed between pentaerythritol and 2-ethylpentanoic acid/2-methylhexanoic acid/2-ethylhexanoic acid/3,5,5-trimethylhexanoic acid. Among them, an ester formed between a carboxylic acid mixture containing 3,5,5-trimethylhexanoic acid and pentaerythritol is more preferred because an ester with a desired viscosity can be prepared. From the viewpoint of thermal stability in the presence of a metal, particular preference is given to a carboxylate mixture formed between pentaerythritol and 2-ethylhexanoic acid/3,5,5-trimethylhexanoic acid and a carboxylate mixture formed between pentaerythritol and 2-ethylpentanoic acid/2-methylhexanoic acid/2-ethylhexanoic acid/3,5,5-trimethylhexanoic acid.
