Usage

Description

2,4,6-Trichloroanisole (TCA) is a monomethoxybenzene derivative, specifically 1,3,5-trichlorobenzene with one hydrogen atom replaced by a methoxy group. It is a white or off-white fibrous powder that is insoluble in water but soluble in benzene, methanol, and dioxane. TCA gradually sublimates at room temperature and is known for causing cork taint in wines, which can be quantified using the supercritical fluid extraction (SFE) method.

Uses

Used in Dyeing Industry:
2,4,6-Trichloroanisole is used as a dyeing auxiliary for polyester fabrics, enhancing the dyeing process and improving the colorfastness of the fabric.
Used in Odor Control:
2,4,6-Trichloroanisole is employed in methods for reducing odors in rooms during remodeling work by removing the causative substances, contributing to a fresher and more pleasant environment.
Used in Water Treatment:
Degradation of 2,4,6-trichloranisole catalyzed by raw bauxite via ozonation in water has been investigated, indicating its potential use in water treatment processes to remove contaminants and improve water quality.

Selective O-methylation of phenols and benzyl alcohols in simple pyridinium based ionic liquids

Synthesis of pyridinium based ionic liquids were reported and applied as catalyst for the selective O-methylation of phenols and benzyl alcohols. The reactions were carried out by using dimethylcarbonate (DMC) as the methylating agent. High selectivity, high yield and recyclability of the ionic liquids are important features of the reactions.

The use of sodium chlorate/hydrochloric acid mixtures as a novel and selective chlorination agent

Sodium chlorate/hydrochloric acid mixtures were used to chlorinate activated arenes and the α-position of ketones. This chlorination method was used to produce selectively mono-, di-, and trichlorinated compounds by controlling the molarity of sodium chlorate. This reagent proved to be much more efficient and easier to handle than chlorine gas.

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) and microwave-accelerated green chemistry in methylation of phenols, indoles, and benzimidazoles with dimethyl carbonate

(Equation Presented) 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) is a novel and active catalyst in promoting the methylation reaction of phenols, indoles and benzimidazoles with dimethyl carbonate under mild condition. Additional rate enhancement is accomplished by applying microwave irradiation. By incorporating tetrabutylammonium iodide, the same microwave reactions can be further accelerated. By combining these acceleration strategies, very low chemical transformations that take up to several days can be performed efficiently in high yield within minutes.
