Anhydrous and anaerobic reaction device and application thereof

Abstract

The invention discloses an anhydrous and anaerobic reaction device and application thereof. The anhydrous and anaerobic reaction device comprises a reaction bottle, a rubber bottle plug and an aluminum cap; the rubber bottle plug and a bottleneck are tightly matched, the cap is arranged outside the bottle plug and buckled on the bottleneck, a through hole is formed in the middle of the aluminum cap, under the effect of external force, the aluminum cap can be fastened to the outer edge of the bottleneck of the reaction bottle, and thus a reaction system can withstand the high temperature and high pressure; and one face of the rubber bottle plug tightly makes contact with the cap, the outer diameter of a hollow rubber cylinder protruded on the other face of the rubber bottle plug is matchedwith the inner diameter of the bottleneck, thus the reaction bottleneck is sealed, an injector is directly applied to add a liquid material into the reaction bottle through the rubber plug without opening the bottleneck, and oxygen or vapor is prevented from entering in the adding process. The anhydrous and anaerobic reaction device is suitable for an anhydrous and anaerobic reaction under the normal temperature and normal pressure, and also suitable for an anhydrous and anaerobic reaction under the high temperature and high pressure; and a solid material and the liquid material can be added separately to avoid the situation that the anhydrous and anaerobic environment of the reaction system is damaged due to addition of the materials.

Description

technical field [0001] The invention belongs to the field of chemical synthesis equipment, in particular to a water-free and oxygen-free reaction device and its application. Background technique [0002] In recent years, anhydrous and oxygen-free reactions have been widely used in modern organic synthesis reactions. For example, the direct construction of unsaturated carbon-carbon bonds in the synthesis of small molecular compounds, due to the participation of organometallic catalysts, most of them need to be carried out under anhydrous and oxygen-free conditions. For reactions that require heating, the reaction device is required to have a certain high temperature and high pressure resistance. Properties (As Shengming. Modern organic synthesis reactions involving metals. Guangzhou: Guangdong Science and Technology Press, 2001: 1-258); in the synthesis of conjugated polymer materials, the content of oxygen in the reaction environment affects the molecular weight of polymer m...

AI Technical Summary

Problems solved by technology

However, the existence of the three-way branch increases the risk of damage to the reaction bottle during the cleaning process, and the addition of solid materials and liquid materials in batches cannot be realized. It is difficult to avoid the entry of air during the addition of solid materials, resulting in Decline in the quality of anhydrous and oxygen-free environment
