Para Formaldehyde CAS30525-89-4 High Quality Powder Of 96%Min Paraformaldehyde

Introduction

Paraformaldehyde has a strong smell of formaldehyde. The dissolution temperature when the degree of polymerization n is 8-12 is 80℃, and the dissolution temperature when the degree of polymerization n is above 12 is 120-170℃. It is insoluble in ethanol, acetone and ether, but soluble in dilute acid. And dilute alkali solution, it decomposes quickly when melted, but it does not have some mechanical properties of plastic, and it cannot process film. This kind of low-polymerization products are unstable polymers and are easily dissolved into formaldehyde solutions. For example, in the production of amino synthetic resin coatings, in order to avoid the use of formalin with high water content, low-polymerization paraformaldehyde is usually used. Source of formaldehyde.

Parameter

Application

Using low polymerization degree paraformaldehyde instead of ordinary industrial formaldehyde aqueous solution, in the synthesis of pesticides, synthetic resins, coatings and fumigation disinfectants and other various downstream products of formaldehyde, it can not only reduce the energy consumption of dehydration, but also greatly reduce the waste water. Processing capacity, this is a green environmental protection project that benefits the country and the people. Paraformaldehyde with low polymerization degree is a solid particle because it has higher effective components than industrial formaldehyde, which is beneficial to chemical synthesis and other industrial applications such as chemical industry and pharmacy. Especially in the synthesis that requires the use of anhydrous formaldehyde as a raw material, it has a wide range of uses. . It can also be used as a disinfectant, bactericide, fumigant and herbicide, and to make resin and artificial ivory. Some products are shown in the figure below.
