Chemische Eigenschaften
white crystalline mass, needles or crystals
Verwenden
4-Methylbenzyl alcohol is used in fragrances, flavoring and as a laboratory reagent. It is also used as a raw material for the preparation of polycarbonates and 4-methyl-benzaldehyde.
Vorbereitung Methode
p-Tolyl alcohol is commercially prepared by reducing p-tolyl
aldehyde. It is used mainly in fragrances, and the
major route of exposure is likely to be dermal contact.
