Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of triphenylmethane production, in particular to drying equipment for triphenylmethane production. Background Art
[0002] Triphenylmethane is an organic compound. In the field of chemistry, triphenylmethane is often used as an important protecting group reagent due to its steric hindrance effect and reactivity. It is particularly suitable for the protection of primary alcohols. It can convert primary alcohols into trityl ethers, thereby preventing the further reaction of primary alcohols in subsequent reactions. In addition, it is also a key intermediate in drug synthesis and is widely used in the selective protection of primary hydroxyl compounds such as nucleosides, monosaccharides or polysaccharides, as well as peptide synthesis and other organic synthesis reactions, such as Wittig reaction as an ylide precursor.
[0003] Since triphenylmethane is a moisture-sensitive chemical, excessive water content may affect its quality and subsequent chemical reaction performance, so the moisture content needs to be strictly controlled by drying equipment during the synthesis and purification steps.
[0004] In the prior art, triphenylmethane is usually dried in a drying oven or an oven: the material is dried by circulating hot air or other drying media at room temperature or high temperature. Although this meets the use requirements to a certain extent, the contact area between the triphenylmethane raw material and the hot air inside the drying oven or the oven is small. The small contact area means that the speed and total amount of hot air heat energy received by the raw material surface area per unit time are limited, resulting in a reduced drying rate and requiring a longer drying time to achieve the same drying effect. Utility Model Content
[0005] The utility model aims to provide a drying device for triphenylmethane production, which has the advantage of continuously stirring the raw materials during drying to increase the contact area between the raw materials and the heat source, thereby solving the problem that the contact area is small, resulting in a reduced drying rate and requiring a longer drying time to achieve the same drying effect.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. The utility model uses the cooperation between the toothed disk, the toothed disk, the first gear and the second gear to drive the second gear to rotate in the opposite direction when the mounting disk rotates, and the cooperation between the second gear and the third gear drives the stirring arm and the stirring rod to rotate.
