Description

Technical Field

[0001] The utility model relates to a reaction container for producing and processing hafnium esters, belonging to the technical field of hafnium ester reaction containers. Background Art

[0002] Hafnium ester is a precursor for ultra-high temperature ceramics and a key basic raw material for the preparation of ultra-high temperature ceramic-based composite materials. After years of development, its preparation process has become increasingly mature, and its comprehensive performance has shown obvious advantages, and it has been used in the aerospace field.

[0003] The production process of hafnium esters in industry is mainly based on direct esterification of alcohol and metal hafnium salt, which has a low yield. Hydrogen chloride is generated during the reaction and reacts with alcohol to form chlorinated products, which reduces the yield of hafnium esters. In order to reduce the occurrence of side reactions, vacuuming is usually used to reduce the content of hydrogen chloride in the system. However, the generated hydrogen chloride and the absorbed hydrochloric acid often corrode the equipment, and the hydrogen chloride removed from the system by vacuum also carries some raw materials, which increases the loss of alcohol and metal hafnium salt and greatly increases the consumption of raw materials.

The utility model adds an acid-binding agent during the esterification process to neutralize the generated hydrogen chloride, increase the reaction activity, promote the progress of the reaction, shorten the reaction time, thereby reducing the consumption of raw materials and increasing the yield of hafnium esters.
