Isopropyl-m-cresol

Thymol (isopropyl-m-cresol) is a volatile, phenolic monoterpene produced by several plants including thyme (Thymus vulgaris L.) (Baerheim Svendsen and Scheffer, 1985). Thymol has well-known antiseptic, antifungal, and anthelminthic properties (Wilson et al., 1977) and is also used for food and fragrance applications (Bauer et al., 1990). [Pg.24]

Undesired alkylates of m-cresol (2-,4- and 5-isopropyl-m-cresol, 2,6- and 4,6-diisopropyl m-cresol) are recycled to the reaction zone to achieve a high overall 3neld of desired thymol. [Pg.100]

The synthetic process starts with the isopropylation of m-cresol to yield thymol. After catalytic hydrogenation a mixture of stereoisomers is obtained from which (+)-menthol is isolated. The process requires much separation and recycling work. In contrast, the semi-synthetic process of Takasago (Scheme 5.5) leads essentially to stereopure (—)-menthol [19]. [Pg.107]

Some branched alkyl groups, especially the isopropyl group, can readily be replaced by a nitro group, even when they are attached to an aromatic ring. For example, under certain nitration conditions thymol ethers can yield the corresponding trinitro-m-cresol ethers (Giua [198]). Similarly, the nitration of p- cymene may lead to dinitrotoluene (Alfthan [199]) ... [Pg.129]

Thymol is obtained from the volatile oil of thyme Thymus vulgaris Linne (Fam Labiatae)) by fractional distillation followed by extraction and recrystallization. Thyme oil yields about 20-30% thymol. Thymol may also be produced synthetically from p-cymene, menthone, or piperitone, or by the interaction of m-cresol with isopropyl chloride. [Pg.781]

Another important derivative of m-cresol used in the manufacture of plant protection agents is m-phenoxytoluene, which can be produced from m-cresol and chloro- or bromobenzene at temperatures of 200 °C, with copper catalysts. m-Phenoxytoluene is converted into m-phenoxybenzoic acid methyl ester by oxidation with a cobalt acetate/KBr catalyst and subsequent esterification m-phenoxybenzoic add methyl ester serves as an intermediate in the production of m-phenoxybenzaldehyde, which is used as the raw material in the production of the synthetic pyrethroid insecticide, fenvalerate (see Chapter 6.3.2). The cyanohydrin is formed in-situ, then made to react with 2-isopropyl-(4-chlorophenyl) acetic acid chloride to yield fenvalerate, which was developed by Sumitomo Chemical in 1972. Pyrethroid insecticides are distinguished by their low toxicity and high activity. [Pg.169]
