Camphor producing method and isoborneol dissolving equipment thereof

Abstract

The invention discloses a camphor producing method which comprises a dissolving work procedure and a dehydrogenizing work procedure, wherein the dissolving work procedure comprises the step: dissolving isoborneol crystal and a solvent in isoborneol dissolving equipment to obtain a product; and then the product is put into the dehydrogenizing work procedure to produce a camphor product. The camphorproducing method has the advantages that the dissolving work procedure is added before the dehydrogenizing work procedure, so that the isoborneol can be dissolved more fully, and later reaction is beneficiated. A dual dissolving and heating mode can ensure that the isoborneol is fully dissolved; in clamping sleeve dissolving and heating, less steam can be used for thermal insulation under the completely-dissolved situation; in coil heating, the isoborneol can be quickly dissolved. In the dissolving process, a part of water brought by the iroborneol can be removed; by means of additionally arranging a liquidometer on a water draining pipeline, a current water content situation in a kettle body can be known through the removed water, so that dewatering time of the dehydrogenizing work procedure is reduced.

Description

technical field [0001] The invention relates to a production method of camphor, and to an isoborneol dissolving device used in the method. Background technique [0002] Isoborneol, white crystal, has a smell similar to camphor. It is a forestry chemical product, also known as isoborneol, and its properties are similar to camphor. It is a unique product of the hydration camphor process. Melting point, 212°C, soluble in ethanol, ether, chloroform, petroleum ether. It is used as a spice in daily chemical products and as a preservative. The appearance and properties of white isoborneol are similar to those of camphor, and the cost is low. It is gradually replacing camphor in many fields, and its application prospects are very broad. [0003] In the current camphor (synthesis) production process, isoborneol is used as the product of the hydrolysis process and directly as the feed material of the dehydrogenation process. The quality and dissolution of isoborneol have a considera...

AI Technical Summary

Problems solved by technology

Isoborneol is often incompletely dissolved in the dehydrogenation pot, which increases the consumption of isoborneol, increases the difficulty of subsequent xylene recovery, and even affects the quality of the final camphor (synthesis)

Because there is a catalyst in the dehydrogenation pot, the temperature of the isoborneol crystal must be lowered to below 90°C before feeding, otherwise it will cause spontaneous combustion when it encounters air, and the safety of feeding is poor, and the operation needs to be closely monitored.
