    摘要: Process for producing compounds useful in perfumery including isochromans and acylated indane hydrocarbons with an alkylene oxide or with a lower acyl halide in the presence of a hydrocarbon or hydrocarbon mixture containing C.sub.5 and C.sub.10 alkanes at a temperature of from -20.degree. C. up to -5.degree. C. In the case of forming isochromans, the resulting alcohol is reacted, in situ, with a lower alkanol and a formaldehyde precursor at temperatures of from 20.degree. C. up to 80.degree. C.

    摘要: This invention relates to a two step process for producing p-tolualdehyde which comprises reacting toluene with carbon monoxide in the presence of hydrogen fluoride and boron trifluoride, characterized by mixing all of the toluene, all of the hydrogen fluoride and only part of the boron trifluoride necessary to convert a substantial amount of toluene to p-tolualdehyde, thereby forming a toluene-hydrogen fluoride-boron trifluoride complex and reacting the toluene in the reaction system with carbon monoxide, thereby converting a portion of the toluene to p-tolualdehyde, and then adding the remainder of the boron trifluoride to the reaction product and reacting the remainder of the toluene with carbon oxide.
