METHOD FOR ALKYLATION OF AROMATIC COMPOUNDS AND METHOD FOR INCREASING OF SERVICE TIME OF CATALYST |
摘要 |
FIELD: organic chemistry. SUBSTANCE: alkylation of aromatic compounds is carried out by contacting of olefin and aromatic hydrocarbon, the process is carried out in the presence of catalyst. Before alkylation takes place aromatic hydrocarbon is affected by processing to remove oxygen being dissolved in said hydrocarbon and/or aromatic hydrocarbon is strained. Straining is carried out through stationary layer of particles of aluminium being modified with silver. EFFECT: improved efficiency of the method. 14 cl, 1 dwge
