1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C 10 H 7 CH 2 CO 2 H. This colorless solid is soluble in organic solvents. This colorless solid is soluble in organic solvents. It features a carboxylmethyl group (CH 2 CO 2 H) linked to the "1-position" of naphthalene .
Naphthalene's minimum odor threshold is 0.084 ppm for humans. [44] Mothballs and other products containing naphthalene have been banned within the EU since 2008. [45] [46] In China, the use of naphthalene in mothballs is forbidden. [47] Danger to human health and the common use of natural camphor are cited as reasons for the ban.

The reaction of copper metal with naphthenic acid, which has been used commercially, requires more forcing reaction conditions and generates excessive impurities. [2] Less commonly practiced methods of synthesis include reaction of copper acetate with naphthenic acid, [ 3 ] which generates acetic acid as a byproduct, and electrochemically using ...
Naphthenic acid can refer to derivatives and isomers of naphthalene carboxylic acids. In the petrochemical industry, NA's refer to alkyl carboxylic acids found in petroleum. [3] The term naphthenic acid has roots in the somewhat archaic term "naphthene" (cycloaliphatic but non-aromatic) used to classify hydrocarbons.
N-(1-Naphthyl)ethylenediamine dihydrochloride is widely used in the quantitative analysis of nitrate and nitrite in water samples by colorimetry. It readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored azo compound .
It is used on a large scale to prepare naphthalene dicarboxylic anhydride, which is a precursor to dyes and optical brighteners [3] (such as 1,4-bis(2-benzoxazolyl)naphthalene). Besides that, the anhydride is also the precursor to perylenetetracarboxylic dianhydride, precursor to several commercial pigments and dyes. [7] [8]
acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
