2-クロロベンズアルデヒド

化学的特性2-Chlorobenzaldehyde is a colorless to yellowish liquid with a penetrating odor. Insoluble in water, soluble in benzene, alcohol and ether. 2-Chlorobenzaldehyde is considerably more resistant to oxidation than benzaldehyde. When it is heated with sodium sulfite solution under pressure, benzaldehyde-2-sulfonic acid forms.

用途医薬品、染料中間体、金属処理剤

使用2-Chlorobenzaldehyde can be used to make alcohols, acids, and dyes; used in the rubber, tanning, and paper industries; used as an intermediate for optical brighteners, agricultural chemicals, and pharmaceuticals.It can also be used to prepare triphenyl methane and related dyes, organic intermediate.

一般的な説明2-chlorobenzaldehyde is a clear colorless to yellowish liquid. (NTP, 1992)

製造方法2-Chlorobenzaldehyde is produced mainly by chlorination of 2-chlorotoluene to form 2-chlorobenzal chloride, which is then subjected to acid hydrolysis. Metal salts, such as iron(III) chloride, are used as catalysts. The hydrolysis can also be accomplished using formic acid without a catalyst.2-Chlorobenzaldehyde can also be produced by oxidation of 2-chlorobenzyl chloride with N-oxides of tertiary amines or with dilute nitric acid.https://pubchem.ncbi.nlm.nih.gov/compound/2-Chlorobenzaldehyde

純化方法Wash it with 10% Na2CO3 solution, then fractionally distil it in the presence of a small amount of catechol as stabiliser. [Beilstein 7 H 233, 7 IV 561.]
