Typical Application Case Sharing of Molecular Distillation Equipment

Overview

Molecular distillation is a distillation technique carried out under high vacuum conditions, featuring low distillation temperature, high vacuum degree, short heating time and high separation efficiency. This technology is particularly suitable for the separation and purification of high-boiling-point, heat-sensitive and easily oxidized substances. Yuanhuai has accumulated rich experience in the research and development and application of molecular distillation equipment. The following will demonstrate its successful application in different fields through specific cases.

I. Application Examples of Molecular Distillation Equipment in the Resin Industry

Application of epoxy resin for impurity removal

During the production process of epoxy resin, the products often contain impurities such as epichlorohydrin, composite materials, and electronic chemicals. Traditional separation methods are difficult to effectively remove these impurities, which affects product quality. After adopting molecular distillation technology, each component can be precisely separated under low-temperature conditions, impurities can be effectively removed, and the purity of the product can be improved. This process has been successfully applied to the production of epoxy resin products in high-end application fields such as aerospace and weather forecasting.

Application of acrylic resin for impurity removal

During the production process of acrylic resin, low-boiling-point impurities are generated. The presence of these impurities will affect the viscosity and insoluble monomer content of the product. Through the application of molecular distillation equipment, separation conditions can be precisely controlled, low-boiling-point impurities can be effectively removed, and the purity and quality of the product can be improved. Meanwhile, this technology can also handle different forms of acrylic resin products such as coatings and 㬵 adhesives.

Application of phenolic resin purification

During the production process of phenolic resin, impurities such as monomer phenols may remain. The content of monomer phenol can be reduced to a relatively low level (such as less than 0.01%) by molecular distillation, which can enhance the purity of phenolic resin and improve its performance.

Application of silicone resin purification

During the synthesis of silicone resin, various low-molecular-weight by-products are produced. These substances can affect the thermal stability and quality of the resin. Molecular distillation equipment can precisely separate these by-products, improve the purity of the resin, and expand its application range.

Decolorization and deodorization of resin products

Some resin products may have problems such as unpleasant odors or poor color due to various issues during the production process. Molecular distillation technology can effectively remove odorous substances and colored impurities from resins, improving the quality of the resins.

II. Application Examples of Molecular Distillation Equipment in the Silicone Industry

Application of impurity removal for silicone monomers

During the production process of silicone monomers, a small amount of low-molecular-weight impurities are generated. Although the content of these impurities is very low, they have a significant impact on the performance of the final product. Molecular distillation equipment can precisely remove these trace impurities in any silicone monomer production process, ensuring that the product meets high purity requirements. This technology has been successfully applied to the purification process of various organosilicon monomers.

Optimization of silicone intermediate separation

In organosilicon intermediates, cyclic siloxanes such as octamethylcyclotetrasiloxane are important components. Siloxanes with different cyclic structures have differences in physical and chemical properties. Molecular distillation equipment can achieve the separation and purification of different cyclic siloxanes based on these differences.

Post-treatment of silicone polymers

During the production process of silicone, there are often unreacted monomer substances or solvent residues, which can lead to problems such as impaired product performance or insufficient transparency. Molecular distillation equipment can remove impurities at a lower temperature, improve product quality and appearance, and enhance product performance.

III. Evaluation of Application Effects

 According to the statistics of actual application data, after adopting molecular distillation technology, the purity of the products has generally increased by more than 95%, and the impurity content has been reduced to below 0.01%. In the resin industry application, the thermal stability of the product has increased by 20-30%, and in the silicone industry application, the monomer purity has reached the industrial standard of over 99.9%

Conclusions and Prospects

The successful application of molecular distillation equipment in the resin industry and the silicone industry fully demonstrates the advanced nature and practicality of this technology. With the continuous improvement of product quality requirements in the chemical industry, molecular distillation technology will play an important role in more fields. Yuanhuai Technology will continue to be committed to technological innovation and equipment optimization, providing more efficient, energy-saving and environmentally friendly separation solutions for the chemical industry. In the future, with the development of strategic emerging industries such as new materials and new energy, the application prospects of molecular distillation technology will be even broader. We believe that through continuous technological innovation and process optimization, molecular distillation equipment will make greater contributions to the transformation and upgrading of the chemical industry.
