A process for preparing benzoic acid by oxidizing toluene with a molecular oxygen containing gas in the liquid phase, which is characterized in that the oxidation is performed in the substantial absence of lower fatty acids and/or halogen compounds, and in the presence of a catalyst composed of...
8. The method of claim 3, wherein the diester species formed is selected from the group consisting of decanoic acid 2-decanoyloxy-1-hexyl-octyl ester and its isomers, tetradecanoic acid 1-hexyl-2-tetradecanoyloxy-octyl esters and its isomers, dodecanoic acid 2-dodecanoyloxy-1-hexyl-octyl este...
Then the temperature was elevated to 90 °C and 5-hydroxy-1-cyclooctene (0.004 mol) in 10 mL toluene was added slowly into the system within 1 h under argon atmosphere. The reaction was kept at 90 °C for another 24 h to obtain cyclooctene-PEG macromonomer. The yield of cyclooctene-...
(HCF) composite, which uses a much cheaper benzoic acid (BA; the cost of the analytical-grade product is 16.4 ¥/250 g) as the ligand to replace part of the traditional ligand trimesic acid (H3BTC to synthesize HKUST-1; the cost of the analytical-grade product is 566 ¥/500 g);...
epoxy resin useful as a hardener for coatings, etc., economically, an industrial scale, by reacting p-oxybenzoic acid with an epihalohydrin in the presence of a basic catalyst, separating the unreacted material from the product and further reacting the product with a specific amount of a base...

In addition, the coating method does not obtain a sufficient melting point drop of diacetal in comparison with a large amount of coating agent such as aliphatic carboxylic acid amide and / or aromatic carboxylic acid amide, and the amide compound is bleeded in the polyolefin molded body. ...
We have succeeded in obtaining whiskers of POB and other aromatic polyesters using crystallization of oligomers during solution polymerization.10–19 POB whiskers are prepared from p-acetoxybenzoic acid (p-ABA) in poor solvent such as liquid paraffin (LPF) with the elimina- tion of acetic acid ...
