Production of Acetaldoxime or Acetaldehyde Oxime. Exploring Business Opportunity in Chemical Industry.
Acetaldehyde Oxime is prepared by oximating acetaldehyde with an aqueous hydroxylamine-containing solution to form an aqueous oximation reaction mixture which includes a salt and recovering acetaldehyde Oxime from the aqueous oximation reaction mixture by distilling a mixture of acetaldehyde Oxime and water directly from the aqueous oximation reaction mixture. The existence of an azeotrope between water and acetaldehyde Oxime enables all the acetaldehyde Oxime to distill out of the aqueous oximation reaction mixture without large amounts of excess water being distilled, which could undesirably concentrate acetaldehyde Oxime in the bottoms of the distillation, leading to product decomposition or side reaction.
The recovered mixture containing acetaldehyde Oxime and water and lites including acetaldehyde and ammonia is then purified by a second or lights distillation to remove the lights including acetaldehyde and water and produce a product mixture of acetaldehyde Oxime and water relatively free of lights. This product mixture may then be diluted and reacted with Cl2.

Oxime are chemical compounds having the general formula >C=NOH. They belong to the imine family. Oxime are generated by the condensation of an aldehyde or a ketone with hydroxylamine. During condensation aldehydes produce aldoxime similarly ketones produce ketoxime. Oxime exist as colorless crystals and are poorly soluble in water. Oxime can be hydrolyzed in the presence of various inorganic acids, and they decompose into the corresponding ketones or aldehydes, and hydroxylamines. The reduction of Oxime compounds produces the corresponding amine compounds.
Uses and Applications
Acetaldoxime is used as an oxygen scavenger in boiler water. It is also used as an intermediate in chemical synthesis and pharmaceuticals. It is involved in the rearrangement reaction to prepare acetamide by using nickel acetate as a catalyst. It acts as a precursor to prepare heterocyclic compound such as spiroisoxazoline. Further, it is used to prepare alkylated (Z)-Oxime by deprotonating followed by reaction with benzyl bromide.
Acetaldehyde Oxime (AAO) is an essential raw material used in the production of pesticides that are used to protect crops from insect and fungus infestation. AAO is also used in small quantities in the production of certain types of coatings.

This growth can be attributed to the increasing demand for acetaldehyde in the water treatment application. In addition, the demand for high-quality derivatives in emerging economies is another significant factor contributing to the growth of the acetaldehyde market. Based on application, acetaldehyde finds use in a wide range of applications, such as chemicals, plastics & synthetic rubber, food & beverage, paints & coatings, pharmaceuticals & cosmetics, paper & pulp, water treatment, and others. The food & beverage segment is the largest application segment of the acetaldehyde market. The food & beverage application leads the overall acetaldehyde market, due to its use as a flavoring agent in several food products.
In the food & beverage industry, acetaldehyde is used in the production of preservatives and flavorings. Furthermore, it occurs naturally in fruits and fruit juices, ripe fruits, cheese, and heated milk. Acetaldehyde arises naturally during fermentation and is found in low levels in foodstuffs such as milk products, soy products, pickled vegetables, and nonalcoholic beverages. Acetaldehyde acts as an additive in fruit and fish preservatives and flavoring agents, as well as a cross-linker in gelatin hardening. Furthermore, it is also used in producing vinegar and fruit and fish preservative. Acetaldehyde is mainly used to produce other chemicals, such as disinfectants, drugs, perfumes, explosives, lacquer and varnishes, photographic chemicals, phenolic, and urea resins, rubber accelerators and antioxidants, and room air deodorizers.
