o-Cymene is an organic compound classified as an aromatic hydrocarbon. Its structure consists of a benzene ring ortho -substituted with a methyl group and an isopropyl group . It is a flammable colorless liquid which is nearly insoluble in water but soluble in organic solvents.
The biodegradation of p-Chlorocresol [8] is done in the liver, and then excreted primarily via the kidneys or in smaller amounts through the lungs. In facultative Thauera sp. strain DO, p-Chlorocresol was degraded aerobically either by dehalogenation followed by catechol degradation pathway, or methyl oxidation to 4-chlorobenzoate. [9]
Like other terpenes, the ocimenes are nearly insoluble in water, but soluble in common organic solvents. The name is derived from the plant genus name Ocimum [ 4 ] from the Ancient Greek word for basil , ὤκιμον ( ṓkimon ).
ch 3 c 6 h 5 + 2 ch 3 ch=ch 2 → ch 3 c 6 h 4 ch(ch 3) 2 These alkylations are catalyzed by various Lewis acids , such as aluminium trichloride . m- and p-Cymene are mainly of interest as precursors to the respective cresols , which exploits the Hock rearrangements .
In addition to p-cymene, two less common geometric isomers are o-cymene, in which the alkyl groups are ortho-substituted, and m-cymene, in which they are meta-substituted. p-Cymene is the only natural isomer, as expected from the terpene rule. All three isomers form the group of cymenes. Cymene is also produced by alkylation of toluene with ...
Why hydration is important. This bonanza of new hydration products plays to a basic but critical need: More than 50% of people around the globe, including in the U.S., are chronically ...
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), C 10 H 14 O, is a natural monoterpenoid phenol derivative of p-Cymene, isomeric with carvacrol.It occurs naturally in the oil of thyme, and it is extracted from Thymus vulgaris (common thyme), ajwain, [4] and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties.
