Abstract

The invention discloses an intellectualized method for preparing purified indigo. A distillation extraction device is used and comprises a reaction machine body and a distillation machine body arranged on the end face of the top of the reaction machine body, a reaction cavity with an upward opening is formed in the reaction machine body, and a distillation cavity communicated with the reaction cavity is formed in the distillation machine body; a partition plate is arranged at the top of the reaction cavity, symmetric first guide slide grooves located at the two ends of the distillation cavityare formed in the distillation machine body, and second guide slide grooves are formed and communicated between the first guide slide groove and the distillation cavity; an opening runs through the interior of the wall of the distillation cavity, a power machine body is arranged at the top of the distillation machine body, and a first cavity is formed in the power machine body; a first motor is embedded in the inner wall of the top of the first cavity, and a first belt wheel is in power connection with the tail end of the bottom of the first motor.

Description

technical field [0001] The invention relates to the technical field of indigo preparation, in particular to an intelligent method for preparing purified indigo. Background technique [0002] With the development of science and the progress of society, the country has been promoting the development of advanced technology. Among them, there has always been a relatively difficult technical problem in the field of indigo preparation technology. The currently used indigo preparation methods include aniline and chloroacetic acid or aniline. , cyanic acid and formaldehyde to form a N-phenylglycine, and then the salt is melted with alkali at high temperature to convert it into a 3-indoxyl compound, and then the compound is oxidized with air. However, these methods are not only complicated due to many steps, but also use a large amount of KOH and NaOH. In addition, the disadvantage of recovery and reuse of used KOH and NaOH is that it consumes too much energy and requires special eq...
