The synthesis of feruloylated monoacylglycerol catalyzed by P-Toluene sulfonic acid was investigated.

By the improved method, proglumide was synthesized in acetic anhydride with toluene as the dehydrating agent.

A survey of the health condition of 308 cases of workers exposed to benzene, toluene, xylol and mixed derivatives of benzene is presented.

Used as a component of solvents in the process of the azeotropism, and could partly replace toluene, xylene and methyl isobutyl ketone (MIBK).

Citral was synthesized by catalytical rearrangement of dehydrolinalool in toluene solution with the present of molybdenyl acetylacetonate, benzoic acid and dimethyl sulfoxide (DMSO).

No osmyl and no taste.Soluble in Benzene,Acetone,C2H4Cl2,CS2,toluene,party soluble in alcohol,diethyl ether,insoluble in water,gasoline.

It was found that when the oxidation reaction was performed in toluene solvent, benzyl alcohol was oxidized to benzaldehyde without any overoxidation to benzoic acid;

Toluene diisocyanate (TDI) is one of the most useful kinds of isocyanateth that is produced by the method of phosgenation of amine.

Ethyl cellulose was synthesized successfully in one step based on reaction of cellulose with excess chloroethane and sodium hydroxide in toluene as diluent.

Firstly, p-methylacetophenone was obtained in the presence of alchlor as the catalyst, and the optimum condition was 4:1:2 in molar ratio for toluene, acetic anhydride and alchlor with yield of 86.2%.

Two series of thermotropic liquid crystalline polyureas were synthesized by the copolymerization of benzidine (or o-tolidine),1,6-hexane diamine and 2,4-toluene diisocyanate.

The effects of the catalyst dosage and the preparation conditions of HZ-1 zeolite,for example, number of exchange times on the benzoylation of toluene were studied.

Four kinds of methods to synthesize o-Dichlorobenzaldehyde were introduced. the advantages of hydrolysis methods to reduce p-toluene sulfonyl chloride were discussed.

The isomer ratio of o-MNT to p-MNT,the degree of dinitration and the ratio of 2,6-DNT to 2,4-DNT have been investigated in the mononitration product of toluene by mixed acid.

The system condition of chromatography separating 2,6—2,4—2,3— and 3,4—toluenediamine isomer and the test methods verifying purity for toluene-diamine reference materilas were studied by HPLC.
