| abstract |
Process for the preparation of Phenolic thiocarboxylic acid esters Abstract of the Disclosure A process for the preparation of compounds of formula I (I), by reacting a phenol with formaldehyde and a thiol of formula HS-Cn-H2n-COO-R3 under excess pressure and in the presence of dimethylamine. R1 and R2 are each independently of each other C1-C4 alkyl, R3 is C1-C20 alkyl or C2-C20 alkyl which is interrupted by -O- or -S- and n is 1 or 2. The compounds of formula (I) are useful antioxidants. |
