Toxicity | LD50 orally in rats: 3.25 ml/kg (Smyth) |
White needle-like crystals. There are phenolic-like Woody and sweet aroma.
obtained by heating phenol with isobutene in the presence of zinc chloride or with tert-butanol in sulfuric acid as catalyst at 100 °c. The crude product can be recrystallized from ethanol to obtain the desired product.
It is mainly used as an intermediate for synthesizing oil-soluble phenolic resin, ink, rubber coating, flame retardant, pesticide, perfume, etc. Trace for daily chemical essence.
The acute oral LD50 of rats is 0.56-3. 5g/kg, and the percutaneous LD50 of rabbits is 7.5g/kg. After 1 day of application of the product to the skin of rabbits under closed conditions, irritation was observed. With 1% Vaseline preparation on human closed skin contact test, coated two days later found no irritation.
