Cumic aldehyde

They also identihed tI-/3-pheIlaDdrenc and cumic aldehyde. [Pg.452]

Cumic aldehyde, or isopropyl-benzaldehyde, is present in cummin oil and in the oils of boldo leaf, cassie flower oil, and, probably, in certain eucalyptus oils. It is an oil of powerful odour, having the formula C,gHi.20. Its characters are as follows —... [Pg.195]

This aldehyde has been isolated from various Eucalyptus oils by Baker and Smith. It has a pleasant odour resembling that of cumic aldehyde, with which Schimmel Co. have considered it to be identical. This, however, is improbable, and Baker and Smith consider it to have the formula CjHjjO, which would make it to be a lower homologue of the terpenic aldehydes. Its physical characters, however, are somewhat doubtful, as specimens isolated from the oils of Eucalyptus hemiphloia and Eucalyptus salubris show. These are as follows —... [Pg.209]

From the bisulphite liquors from which the double compounds of the aldehydes mentioned above had separated as solid products, a small quantity of an aldehyde was obtained which had the odour of oumic aldehyde. Its semi-carbazone melted at 201 to 202, and yielded on combustion values corresponding to those calculated for the semi-carbazone of cumic aldehyde. [Pg.140]

According to Schimmel Co. this oil contains ji-cymene, cineol, and ascaridol, C qHj,02. Traces of terpenes and phenols are also present. Tardy has reported on an oil under this name which had a specific gravity 0-876, and optical rotation - 6° 30. It contained a-pinene, dipentene, terpineol, cumic aldehyde, eugenol, sesquitei-penes, and acetic esters. [Pg.178]

The odour is distinctly sweeter than the normal cummin oil and a. little more reminiscent of caraway, although, from the figures above indicated, it does not seem to contain a higher percentage of cumic aldehyde. Carvone does not appear to be present. ... [Pg.314]

From the fraction 175 to 177 (specific gravity = 0 8469, optica rotation = -i- 55 7 ) a tetrabromide melting at 120 and a nitrosochloride melting at 93 to 95 were obtained. This fraction appears to be a mixture of dipentene and dea tro-limonene. The oil consists of terpenes to the extent of about 90 per cent. The fractions boiling over 180 were treated with sodium bisulphite, and the compound formed treated in the usual manner, when a body was liberated which was found to be cumic aldehyde, which was identified by its forming a semi carbazone melting at 210 , and by oxidation to cuminic acid melting at 115. In the fraction... [Pg.451]

They also identified d-/8-phellandrene and cumic aldehyde. [Pg.452]
