Abstract
The invention discloses a dehydration treatment method of peppermint oil, which comprises the following steps of: checking whether a vacuum pump, a dehydration tank and related valves are in good condition or not; adding primary cerebrol into the dehydration tank to a stipulated liquid level, then opening steam to heat, opening the vacuum pump to vacuumize so as to remove moisture and a small amount of components with low boiling point, condensing the moisture of a low-boiling-point substance through a condenser, then collecting into a collector, placing into a water separation tank after dehydration completes, and recycling the oil content of an upper layer; finishing dehydration, closing the vacuum pump, pouring the oil into a plate-and-frame filter press by using the pump when oil temperature is reduced to 65-75 DEG C, feeding the filtered cerebrol into a distributing tank, placing oil-water in a receiving groove into the water separation tank, and recycling light oil. Compared with the prior art, the dehydration treatment method of the peppermint oil has the remarkable advantages that a menthol crystal prepared through the invention has high yield and favorable quality.
Description
Technical field
The present invention relates to a kind of preparation process of chemical reagent, what be specifically related to is a kind of dehydration treatment method of TK-10.
Background technology
Conventional TK-10 prepares in the process, and often because the condition control of this step of dehydration is improper, the TK-10 of producing yields poorly, of poor quality.
Summary of the invention
Goal of the invention: the objective of the invention is to disclose a kind of furnace drying method of TK-10 in order to solve the deficiency of prior art.
Technical scheme: the dehydration treatment method of spearmint oil of the present invention, its objective is such realization: the dehydration treatment method of spearmint oil may further comprise the steps:
(1) looks into vacuum pump, water knockout and have closing valve whether intact;
(2) from after first cerebrol adding drain sump to the regulation liquid level of freezing parser or first cerebrol basin; Open Steam Heating; And drive vavuum pump and vacuumize; To remove moisture content and a small amount of low boiling composition; The moisture low-boiling-point substance is after condenser condenses; Be collected in the gatherer; Dehydration puts it into diversion box after finishing, and reclaims the upper strata oil content; In the dehydration; Vacuum and oily Wen Jun remove and progressively improve with moisture content, and vacuum finally should remain on 0.096-0.099Mpa, and steam pressure is controlled at 0.3-0.4Mpa; The oil temperature should be at 95-100 ℃, and the operating time needs about 6 hours altogether;
Just the dehydration operation of cerebrol, two first cerebrols, ice oil is the same.
(3) dehydration finishes, and stops vacuum pump, when treating oily temperature drop to 65-75 ℃, with pump oil is squeezed into pressure filter filtering mechanical impurity, and the cerebrol after the filtration is sent into material-compound tank, and the profit in the groove is gone into diversion box, reclaims light oil.
More than the timely record of each step operation, in time put in order after hours, improve record.
Beneficial effect: the dehydration treatment method of spearmint oil of the present invention compared with prior art, its remarkable advantage is: the TK-10 output through the present invention preparation is high, and quality is good.
