METHOD OF PREPARING 2,6-DI-TERT. BUTYLPHENOL |
摘要 |
2,6-Di-tert-butyl phosphate is prepared by alkylation of phenol by means of isobutylene at elevated temperature. The reaction is carried out in the presence of an aluminium-containing catalyst. This catalyst is phenoxy-ortho-tert-butylphenoxyhydroaluminic acid of the formula [(OC6H5)n(ortho-tert-C4H9C6H4O)mAl]H, in which n and m are 1 to 3 and n+m is 4. The compound obtained can be used for the preparation of phenol stabilisers, which can themselves be employed for the stabilisation of synthetic rubber, plastics and synthetic fibres. |
