Diphenyl isooctyl phosphite is an important chemical raw material, widely used in plastics, rubber, lubricants and other fields. This article will introduce the manufacturing method of diphenyl isooctyl phosphite, including raw material preparation, reaction process, post-treatment and so on.

1. Raw Material Preparation

The main raw materials for the manufacture of diphenyl isooctyl phosphite include phenol, isooctanol and phosphorous acid. In order to ensure the quality and yield of the product, it is necessary to select raw materials with higher purity and carry out strict quality control.

2. reaction process

1. esterification reaction

of phenol and isooctyl alcohol according to a certain molar ratio into the reactor, heating to a certain temperature, adding catalyst, esterification reaction. Esterification reaction is a reversible reaction, and it is necessary to control the reaction temperature and pressure to promote the reaction to the direction of the product. At the same time, the composition of the reaction solution needs to be sampled and analyzed regularly to determine the progress of the reaction.

2. phosphite esterification reaction

When the esterification reaction to a certain extent, the phosphorous acid added to the reaction kettle, continue to heat the reaction. Phosphorous acid reacts with phenol to form diphenyl phosphite and with isooctanol to form diisooctyl phosphite. It is necessary to control the reaction temperature and time to ensure that the phosphorous acid can fully react.

3. Post-treatment

After the reaction is completed, the reaction solution is cooled to room temperature, and post-treatment operations such as filtration and distillation are performed to obtain a diphenyl isooctyl phosphite product with high purity. It should be noted that the operating conditions need to be strictly controlled during the post-treatment process to avoid decomposition and loss of products.
Precautions for
3.

1. The quality and proportion of raw materials need to be strictly controlled during the manufacturing process to ensure product quality and yield.
2. It is necessary to control the reaction temperature and pressure to promote the reaction and avoid the decomposition and loss of the product.
3. In the post-treatment process, the operating conditions need to be strictly controlled to ensure the purity and yield of the product.

In short, the manufacturing method of diphenyl isooctyl phosphite needs to master certain chemical principles and operation skills, and at the same time, it needs to strictly control the quality of raw materials and operating conditions to ensure the quality and yield of the product.
