Diallylamine is an important organic chemical used in the production of color fixatives and other chemicals. A color fixative is a chemical used for dyeing that causes dyes to form a stable bond on fibers or other materials, thereby preventing the dyes from fading or peeling off during washing or use. The production of color fixatives requires high quality diallylamine.

The production of diallylamine is usually done by cyanidation or hydrogenation. Cyanidation involves the reaction of acrylonitrile and ammonia in the presence of a catalyst to obtain diallylamine. Hydrogenation involves the reaction of propylene and ammonia in the presence of a catalyst to obtain diallylamine. Both methods require strict reaction conditions and catalyst selection to ensure the purity and quality of the product.

During the production of diallylamine, the following aspects need to be noted:

1. Feedstock selection: Select high purity acrylonitrile and propylene, and high purity ammonia. The purity of the raw materials has a great influence on the quality of the products.

2. Control of reaction conditions: The reaction needs to be carried out under certain temperature, pressure and presence of catalyst. The reaction rate and the purity of the product should be controlled during the reaction.

3. Separation and purification of products: Impurities may be present in the products and need to be removed by the separation and purification process. The methods of separation and purification include distillation, crystallization, extraction, etc.

4. Quality testing of the product: testing the purity, impurity content, physical properties, etc. of the product to ensure that the quality of the product meets the requirements. The process of producing color fixing agent from diallylamine requires attention to the type and application of color fixing agent in order to determine the required amount and quality requirements of diallylamine. The type and application of color fixing agents determine the quality and purity requirements of diallylamine.

In conclusion, diallylamine is one of the important raw materials for the production of color fixing agents and other chemicals, and the production process needs to pay attention to the selection of raw materials, the control of reaction conditions, and the separation and purification of products to ensure that the quality of the products meets the requirements.
