Urea phosphate is an important raw material for the production of chemicals, which is widely used in agriculture, medicine, daily chemicals and other fields. In this paper, we will introduce the manufacturing method of urea phosphate, including the steps of raw material preparation, reaction process, and post-treatment.
I. Raw material preparation
1. Urea: urea is one of the main raw materials for the production of urea phosphate, which is used to react with phosphoric acid to generate urea phosphate.
2. Phosphoric acid: Phosphoric acid is another important raw material used to react with urea to produce urea phosphate.
2. Reaction process
1. Urea and phosphoric acid are added into the reactor according to a certain molar ratio and stirred well.
2. At a certain temperature, urea and phosphoric acid react to produce urea phosphate and water.
3. The reaction temperature and time are controlled to ensure that the reaction proceeds completely.
4. pH adjustment of the reaction solution is carried out to bring it to the desired range.
3. Post-treatment
1. Filter the reaction solution to remove impurities and solid particles.
2.
2. The filtrate is evaporated and concentrated to obtain urea phosphate concentrate.
3. The concentrate was cooled and crystallized to obtain urea phosphate crystals.
4. Centrifugal separation and drying of urea phosphate crystals are carried out to obtain the final urea phosphate product.
4. Precautions
1. In the production process, the reaction temperature and time need to be strictly controlled to ensure complete reaction.
2. The quality and purity of raw materials have high requirements to ensure product quality.
3. In the post-treatment process, attention needs to be paid to prevent the product from absorbing moisture and caking.
In short, the manufacturing method of urea phosphate requires strict control of the process parameters of each step to ensure product quality and production efficiency. At the same time, safety management and environmental protection measures in the production process need to be strengthened to ensure the smooth progress of the production process.
