Description
Technical field
The invention belongs to the preparing technical field of organo-peroxide, be specifically related to a kind of preparation method of Lucidol
Background technology
Lucidol is also claimed BPO, and English name is: Dibenzoyl peroxide (being called for short BPO).Its molecular formula is: C
14
H
10
O

Molecular weight is: 242.22; Structural formula is:
BPO is a kind of broad-spectrum diacyl organic peroxide, the particulate state that is white in color, and little have a bitter almond odor, belongs to strong oxidizer.It also can be used as the linking agent of Zylox and viton, the anti-oxidation and antisepsis additive of fodder industry mainly as vinyl monomer polymerization starter and unsaturated polyester class solidifying agent.In addition, also can be used as SYNTHETIC OPTICAL WHITNER and oxygenant, be used for decolouring of the brightening of greasy exquisiteness, flour, fiber etc.And in medicine industry, often be used to be mixed with the various external application agent that are used to treat diseases such as tetter such as acne and chronic ulcer.
are present, and suitability for industrialized production BPO has several different methods.The method that China produces BPO mainly is a Benzoyl chloride 99min. highly basic oxidation style; The main technique flow process of this method is: be furnished with to one and drop into liquid caustic soda and the ydrogen peroxide 50 that measures in the reaction kettle of whipping appts and temperature measuring equipment; And controlled temperature drips Benzoyl chloride 99min. to wherein pressing proportioning again, and needs temperature of reaction is controlled at about 5 ℃ about 5 ℃; After reaction finishes, through filter, wash and separate the BPO finished product.According to another patent CN92102801.6 (publication number CN1065263A) report, can adopt bicarbonate of ammonia or sodium hydrogencarbonate to replace sodium hydroxide, and be equipped with the method production BPO of sodium lauryl sulphate or sodium laurylsulfonate tensio-active agent.U.S. Pat 3674858A also discloses the method for a kind of benzoyl oxide and alkali-metal perborate prepared in reaction BPO.But aforementioned production method is traditional interrupter method, and level of automation is low, exists operation labour intensity high, and big to operative employee's Health hazard, it is high to produce requirement of shelter, and product yield and purity are low, the outstanding shortcoming of the wayward grade of quality product.
have proposed the injector continuous processing BPO production technique through a kind of uniqueness in " recur and produce the Lucidol Study on Process " literary composition of " thermosetting resin " 1997 the 12nd the 4th phases of volume 26-28 page or leaf publication.But pointed out that this technology required equipment is many in " preparation method of Lucidol inquires into " literary composition of " application chemical industry " 2002 the 31st the 6th phases of volume 1-2 page or leaf publication subsequently, floor space is big, still is in the experimental study stage, remains further perfect; Simultaneously, according to the first principles analysis of chemical reaction and chemical process, utilize unique injector to reach vaporific reaction the contact of reaction mass is increased greatly although be; But this still is far from is the contact of molecular level; Far can not accomplish this reaction moment, in addition, the finely powdered product of formation is also very difficult in subsequent disposal; And no matter be from microcosmic or macroscopical aspect; The temperature control that heat transfer problem must be paid close attention to superoxide production becomes very difficult, so that safety in production is difficult to realization, so the industrial applications report is not also arranged when the inventor applies for as yet.
therefore; Seek that a kind of equipment and processing requirement are not harsh, level of automation is high; Can reduce labour intensity; Reduce and produce danger, the technical problem that the process method of the industriallization continuous production BPO of raising yield and quality has become industry to pay close attention to and urgently expect to solve.To this, the inventor follows the ultimate principle of chemical reaction and chemical process, and has carried out long-term exploration and practice repeatedly, has found the way of dealing with problems, and the technical scheme that will introduce below produces under this background
