Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature water baths, in particular to a low-temperature constant temperature reaction bath. Background Art

[0002] Common forms of low-temperature constant-temperature reaction baths include water baths, oil baths, and salt baths. Water baths are a common type, especially in laboratories such as biochemistry and molecular biology, while oil baths and salt baths are usually used for experiments that require higher temperatures. These reaction baths can provide a large amount of heat capacity, that is, they can absorb or release a large amount of heat without temperature fluctuations, thereby ensuring the stability of the reaction process. Low-temperature constant-temperature reaction baths can be used for the synthesis of intermediates such as methylaminoacetaldehyde dimethyl acetal. At the same time, low-temperature constant-temperature reaction baths can also be used in the synthesis of other pharmaceutical intermediates.

[0003] In the actual use of the existing low constant temperature reaction bath, the raw materials cannot be placed in the center of the heating device during the placement process, and thus the raw materials cannot be heated evenly during the heating process, which affects the water bath effect of the raw materials.
