Usage

General Description

N,N-Dimethylhydroxylamine is a chemical compound with the formula (CH3)2NOH. It is a clear, colorless liquid with a sharp, fishy odor and is highly flammable. N,N-Dimethylhydroxylamine is primarily used in industrial processes as a reducing agent and as a stabilizer for water treatment chemicals. It is also used in the production of pharmaceuticals, polymers, and pesticides. N,N-Dimethylhydroxylamine is highly reactive and can pose a serious hazard if not handled properly, as it can form explosive mixtures with air and react violently with oxidizing agents. Due to its hazardous nature, it is important to handle and store this chemical with caution and in compliance with proper safety protocols.

Method for coproducing vasoxine hydrochloride and N,O-dimethylhydroxylamine hydrochloride

The invention relates to the technical field of compound synthesis methods, particularly a method for coproducing vasoxine hydrochloride and N,O-dimethylhydroxylamine hydrochloride. The method comprises the following steps: carrying out methylation reaction on hydroxylamine salt under alkaline conditions by using a methylating agent to obtain a reaction solution containing vasoxine and N,O-dimethylhydroxylamine, rectifying to separate a vasoxine bottom solution and an N,O-dimethylhydroxylamine crude distillate, respectively adding hydrochloric acid for salification, concentrating and crystallizing under reduced pressure, cooling, carrying out vacuum filtration, recrystallizing with water or methanol, and drying to obtain the vasoxine hydrochloride product and N,O-dimethylhydroxylamine hydrochloride product. The method has the advantages of simple and reliable technique, high product quality, high total yield and low comprehensive cost, and is more friendly to the environment and suitable for industrial production.

METHODS FOR CONVERSION OF TYROSINE TO P-HYDROXYSTYRENE AND P-HYDROXYCINNAMIC ACID

Three different reaction steps were combined to provide methods for preparing p-hydroxystyrene and p-hydroxycinnamic acid monomers from tyrosine. The three steps include reductive alkylation of tyrosine, followed by oxidation to the N-oxide, and thermal Cope elimination. During Cope elimination, either p-hydroxycinnamic acid or p-hydroxystyrene was produced depending on the absence or presence of base, respectively. Additionally, p-acetoxystyrene may be prepared by reacting the prepared p-hydroxystyrene either directly or after isolation with an acetylating agent.
