Solubility Behavior of Organic Compounds
Benzoic acid occurs naturally in many plants  and serves as an intermediate in the biosynthesis of many secondary metabolites. Salts of benzoic acid are used as food preservatives. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances.Kate bublikova birthday
Benzoic acid was discovered in the sixteenth century. In Salkowski discovered the antifungal abilities of benzoic acid, which was used for a long time in the preservation of benzoate-containing cloudberry fruits. It is also one of the chemical compounds found in castoreum. This compound is gathered from the castor sacs of the North American beaver. Benzoic acid is produced commercially by partial oxidation of toluene with oxygen.
The process is catalyzed by cobalt or manganese naphthenates. The process uses abundant materials, and proceeds in high yield. The first industrial process involved the reaction of benzotrichloride trichloromethyl benzene with calcium hydroxide in water, using iron or iron salts as catalyst.
The resulting calcium benzoate is converted to benzoic acid with hydrochloric acid. The product contains significant amounts of chlorinated benzoic acid derivatives. For this reason, benzoic acid for human consumption was obtained by dry distillation of gum benzoin. Food-grade benzoic acid is now produced synthetically.
Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value.
It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic solvents for the recrystallization makes this experiment particularly safe. Like other nitriles and amidesbenzonitrile and benzamide can be hydrolyzed to benzoic acid or its conjugate base in acid or basic conditions.
Bromobenzene can be converted to benzoic acid by "carboxylation" of the intermediate phenylmagnesium bromide. Benzyl alcohol   and benzyl chloride and virtually all benzyl derivatives are readily oxidized to benzoic acid.
The phenol can be converted to cyclohexanolwhich is a starting material for nylon synthesis. Benzoate plasticizerssuch as the glycol- diethyleneglycol- and triethyleneglycol esters, are obtained by transesterification of methyl benzoate with the corresponding diol. Alternatively these species arise by treatment of benzoyl chloride with the diol.
These plasticizers are used similarly to those derived from terephthalic acid ester. Benzoic acid and its salts are used as a food preservativesrepresented by the E numbers EEEand E Benzoic acid inhibits the growth of moldyeast  and some bacteria. It is either added directly or created from reactions with its sodiumpotassiumor calcium salt. The mechanism starts with the absorption of benzoic acid into the cell.
The efficacy of benzoic acid and benzoate is thus dependent on the pH of the food. Typical levels of use for benzoic acid as a preservative in food are between 0. Foods in which benzoic acid may be used and maximum levels for its application are controlled by local food laws. Concern has been expressed that benzoic acid and its salts may react with ascorbic acid vitamin C in some soft drinks, forming small quantities of carcinogenic benzene.Please be aware that pubs.

The solubility is high in ethanol, reasonably high in chloroform, lower in toluene, and quite low in the remaining three pure solvents.
In the binary mixtures the solubility of benzoic acid increases with increasing concentration of ethanol. The solubility of benzoic acid increases with increasing temperature.

The Journal of Chemical Thermodynamics, Journal of Molecular Liquids, Benzamide, an inhibitor of poly ADP-ribose polymerase, is a derivative of benzoic acid. Benzamide, an inhibitor of PARP is protective against excitatory amino acid-induced cell death in primary cultures of neurons derived from neonatal rat brain.
In addition, benzamide has more recently been shown to partially prevent the loss of dopaminergic cells and the increase in reactive gliosis caused by METH in vitro in fetal rat mesencephalic cells in culture. Benzamide prevents transformation in a cell cycle-specific manner, maximal prevention coinciding with early S phase, also characteristic of maximal susceptibility to transformation.
Benzamide treatment significantly decreases the iNOS expression and number of apoptotic neurons and thereby improves the neuronal survival and memory during GCI. Only for Reference.
