Product description:Jiangsu Kailin Ruiyang Chemical Co., Ltd. was founded in 2001, the headquarters is located in Liyang City, Jiangsu Province, south of the town of strong town. Is a set of polyol series, UV light curing series, water-based polyurethane series and the new resin
In organic synthesis, acetaldehyde is the second carbon reagent and electrophilic reagent, as the synthesis of CH3CH (OH). It is contracted with three copies of formaldehyde to generate pentaerythritol (CH2OH) 4. The reaction of the reagent and the organic lithium reagent was formed. The synthesis of the Strecker amino acid, acetaldehyde and cyanate and ammonia condensation, can be synthesized by the synthesis of alanine. Acetaldehyde can also be used to construct heterocyclic rings, such as polyacetaldehyde and ammonia to generate pyridine derivatives. In addition, acetaldehyde can be used to make acetic acid, ethanol and ethyl acetate. DDT pesticides are synthesized from acetaldehyde. Acetaldehyde is chlorinated with chloroacetaldehyde. The hydrate of trichloroacetaldehyde is a sleeping pill.
