1-isopropyl-4-phenyl-benzene - Preparation Method
Open Data Verified Data
alkylation of benzene with propylene, acetone, and propyl chloride. The catalysts used are AICl3,H2 S04,H3 P04,HF,BF3, aluminosilicic acid, molecular sieves, etc. The biphenyl and the catalyst are placed in a three-necked flask, and propylene is passed through the bottom of the flask after drying, and reacted through the liquid layer in a bubbling manner at a reaction temperature of 175-200 ℃, and the reaction is completed, the reaction solution was cooled to 80-100 °c while hot, and the filtrate was fractionated to collect a 154-160 °c (1333Pa) fraction. When the catalyst concentration was 6% and the propylene ratio was 0.8, the conversion of biphenyl was 58%, the single pass yield of isopropylbiphenyl was 42% ~ 48%, and the selectivity was above 80%.

1-isopropyl-4-phenyl-benzene - Safety
Open Data Verified Data
The LD50 of rats was 8.5g/kg. Gavage of 0.85g/kg for 15 times resulted in inhibition of central nervous system, reduction of hemoglobin and erythrocyte content, increase of reticulocytes and increase of residual nitrogen in blood by 100%. Has a strong stimulating effect on the skin. Wear protective clothing and gloves to prevent skin contact. See biphenyl for the packaging, storage and transportation of this product.
