Benzene carboxylate

Another pathway takes place upon cyclization of hydrazides of benzene carboxylic acids in the presence of CuCl in an inert atmosphere in DMF. However, only the cyclization of hydrazide 76 (R = H) in conditions of copper catalysis makes it possible to isolate compound 77 (yield 20%). Other hydrazides of acetylenylbenzoic acids react to give a complex mixture of products (Scheme 132) (85IZV1367 85MI2). 

Benzoic acid (benzene carboxylic acid) is a white crystalline solid with a characteristic odor. It is slightly soluble in water and soluble in most common organic solvents.

Based on their chemical structure, the organic chemicals were divided into a number of categories alkanes, alkenes, amines, aromatic hydrocarbons, benzenes, carboxylic acids, halides, phenols, and sulfonic acid. Linear regression analysis has been applied using the method of least-squares fit. Each correlation required at least three datapoints, and the parameters chosen were important to ensure comparable experimental conditions. Most vital parameters in normalizing oxidation rate constants for QSAR analysis are the overall liquid volume used in the treatment system, the source of UV light, reactor type, specific data on substrate concentration, temperature, and pH of the solution during the experiment.

The oxidation of methyl groups of aromatic compounds by CuO-NaOH has been found to be ineffective. Therefore, relatively large amounts of methyl-substituted phenolic and benzene carboxylic acids were isolated from the coal oxidation. 

In an excellent work by Reuter et al. (1983), serious shortcomings in the interpretation of previous oxidation data were demonstrated. They established that mild oxidation of stream humic substances produced large quantities of oxalic acid indicating stream humic substances to be predominantly aliphatic in nature, whereas strong or severe oxidation produced structures stabilized by a 4n -I- 2 overlapping 7r-electron system, attributed mainly to a series of benzene carboxylic acids. Structural interpretation based on the products of severe oxidation would lead one to falsely conclude a greater degree of aromaticity in stream humic substances than actually exists in the unoxidized material.

The highly aromatic character of certain bituminous coals, with a C/H ratio of about 0.8, may offer an interesting source of benzene-carboxylic adds by oxidative cracking. In the presence of potassium salts, these aromatic adds are largely converted to diucids, essentially in the para position. 

Table II includes a representative sampling of a number of Ln-MOFs and CPs built from aromatic linker molecules. Note that this class of materials is dominated by the benzene-carboxylate (and related) species as shown in Fig. 16. This is an attractive linker for a number of reasons, including its planarity and rigidity that to a first assumption, may suggest a more restricted structural diversity when compared to (e.g.) the aliphatics. Despite these features, however, no less rich coordination chemistry or resultant topologies in this family are seen.

The relative adsorption of type 1 isomers on silica is somewhat less clear-cut than on alumina. The lesser importance of sample delocalization on silica [see Eq. (10-5a) and related discussion] should make site chelation on silica less significant than on alumina. Thus the ortho- and para-nitrobenzaldehydes, methoxybenzaldehydes, or dichlorobenzenes are adsorbed on silica to about the same extent (9,20,22a). However, the or// o-dinitrobenzenes, fiuoronitrobenzenes, or chloronitrobenzenes are adsorbed more strongly on silica than are the para isomers (22a,23), suggesting the importance of site chelation.f The relative adsorption on silica of the isomeric methyl esters of the benzene carboxylic acids (51) seems to be controlled by site-chelation. In each case that isomer which has the greatest number of adjacent ester groups is more strongly adsorbed ...
