Toluene diisocyanate (TDI) is an organic compound with the formula CH 3 C 6 H 3 (NCO) 2.Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.
Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. [7]
According to Ogawa and Curran, trifluorotoluene is similar to dichloromethane in standard acylation, tosylation, and silylation reactions. [4] The dielectric constants for dichloromethane and trifluorotoluene are 9.04 and 9.18, respectively, indicating similar solvating properties.
Ethyltoluene is produced by ethylation of toluene: CH 3 C 6 H 5 + C 2 H 4 → CH 3 C 6 H 4 C 2 H 5. Over typical acid catalysts, this process gives a mixture of the 2-, 3-, and 4- isomers. Using a modified zeolite catalyst, the alkylation is shape-selective for the 4- isomer. [1] 4-Ethyltoluene is subjected dehydrogenation to give 4 ...
Together with other isomers, 4-nitrotoluene is prepared by nitration of toluene, [4] commonly using titanium(IV) nitrate. [5] It undergoes the reactions typical for nitrobenzene derivatives, e.g. hydrogenation gives p-toluidine. Oxidation of the methyl substituent of 4-nitrotoluene has been extensively investigated.
Diethyl toluene diamine (DETDA) is a liquid aromatic organic molecule [2] with formula C 11 H 18 N 2. It is chemically an aromatic diamine and has the CAS Registry number of 68479-98-1. It has more than one isomer and the mixture of the two main isomers is given a different CAS number of 75389-89-8. [3]
