Zinc carries out catalysis preparation for catalyst, and this method yield is higher, up to more than 90%.But in product containing a certain amount of aldehyde and
The accessory substances such as unsaturated aldehyde.
CN 1436762 discloses a kind of preparation method, and the method is in the presence of a basic, with the non-of special preparation
Crystalline state Ni is catalyst, is heated, dehydrating condensation, and lattice alcohol yield may be up to 90%.
German Henkel KGAA companies disclose a kind of preparation method speciallyying permit clear 61-6806.1986, the method be
Under conditions of KOH is present, catalyst is made with lead silicate, yield is up to 80%.
Above-mentioned each method can produce different amounts of soap, and accessory substance such as three in product in the preparation process of Guerbet alcohol
Copolymer content is higher, and catalyst cannot be recycled, and serious corrosion is caused to reactor.It is the soap generated except dereaction,
People have done the research work of equivalent.DE-AL-2634676 discloses a kind of method for removing soap, the solution of the method acidifying
Washing separation is carried out to product, the industrial wastewater containing organic matter and heavy metal can be so produced, environment is caused
Pollution.
DE-A-4014736 discloses a kind of method for removing soap, and the method uses the side of the cascade reaction with condenser
Method.Wherein, starting material is recycled and condensed water is separated.Contain metal and soap in cooled product.
DE 1953714 disclose it is a kind of remove soap method, the method be product is filtered at room temperature, is centrifuged,
Extraction removes the soap of indissoluble, but this will produce the waste water of high metal content.
CN1226418 discloses a kind of method for preparing the Guerbet alcohol without metal and without soap, this method avoid logical
Often a large amount of waste water are produced in conventional purge process.The method is obtained the direct separated of Guerbet alcohol, a side by condensation
The product alcohol that face obtains there may be raw alcohol, the catalyst on the other hand obtaining and the high molecular weight product being likely to be obtained, instead
Answering product can discharge from reative cell.But the method is still unavoidable from the generation of soap in course of reaction, so as to influence product to receive
Rate, catalyst cannot recycling utilization.
