Uses

Used in Nitrocellulose Preparations:
Oxamide is used as a stabilizer for nitrocellulose preparations, providing enhanced stability and performance in various applications.
Used in APCP Rocket Motors:
In the aerospace industry, Oxamide is utilized as a high-performance burn rate suppressant in APCP (ammonium perchlorate composite propellant) rocket motors, contributing to improved combustion control and overall performance.
Used in Agriculture:
Oxamide, a diamide of oxalic acid, is a white crystalline and non-hygroscopic fertilizer containing about 32% nitrogen, most of which is water-insoluble at 25°C. It is made from cyanogen hydrolysis in an acid medium and releases nitrogen slowly, making it an ideal choice for use as a slow-release fertilizer. Oxamide is decomposed by soil micro-organisms in the soil, providing a sustained supply of nitrogen for plant growth.

Safety Profile

Poison by ingestion and intraperitoneal routes. An eye irritant. When heated to decomposition it emits toxic fumes of NOx. See also AMIDES.

Purification Methods

Crystallise oxamide from water, grind it and dry it in an oven at 150o. [Beilstein 2 IV 1860.]

Efficient dimerization of formic acid in aqueous solution induced by Ar-Arc plasma

Introduction of argon-arc plasma into an aqueous solution of formic acid resulted in the formation of oxalic acid. The reaction conditions for the dimerization were studied. The maximum yield of oxalic acid reached 47-50% when the reaction was carried out using sodium formate or calcium formate. Dimerization of acetic acid was also examined.

Preparation method of oxamide

The invention provides a preparation method of oxamide. The preparation method comprises the following steps: an intermediate oxamide derivative is prepared from CO, O2 and amine compounds as raw materials by oxidation and carbonylation under the action of a catalyst 1, and then, oxamide is prepared through aminolysis of the oxamide derivative under the action of a catalyst 2. A novel method is used for coproducing oxamide and the oxamide derivative, and the problems that oxalate synthesis materials are poisonous, catalyst efficiency is low and the like in the original technology for synthesizing oxamide through aminolysis of oxalate are solved. Besides, the technologically synthesized oxamide derivative has good substrate applicability and can be applied to fields of medicine, pesticides,synthetic ligands, food additives and the like.

Process method of co-production of oxamide and carbamic acid ester through ammonia ester exchange method

The invention discloses a process method of co-production of oxamide and carbamic acid ester through an ammonia ester exchange method. According to the process method, urea and oxalic acid diethyl serve as raw materials, and two products, namely the oxamide and the carbamic acid ester, can be obtained at the same time through a series of ammonia ester exchange reactions. By means of the process, the problems that products are singular, and by-products affect the reaction process in an original technology for synthesizing oxamide through oxalic acid diethyl ammonolysis and a technology for synthesizing carbamic acid ester through urea alcoholysis are solved; besides, due to the fact that urea is obtained through CO and NH synthesis, NH is replaced with urea, and the process method has active significance in converting CO into high added-value chemicals and efficiently utilizing CO.

Chemical evolution of simple amino acids to asparagine under discharge onto the primitive hydrosphere: Simulation experiments using contact glow discharge

Asparagine is an important amino acid for abiotic polypeptide synthesis. In simulation experiments, it was obtained in 3.0% yield (based on the amount of consumed alanine) from alanine (100 mM) and formamide (200 mM) by contact glow discharge (Harada discharge) onto aqueous solutions. The present results suggest that asparagine could be abiotically synthesized from simple amino acids under possible primitive earth conditions.
