The invention provides a method for preparing silanol by silane hydrolysis, which comprises the following steps of: reacting silane serving as a reaction raw material, water serving as an oxide and a metal compound serving as a catalyst to obtain silanol; wherein the molecular formula of the silane is SiHR1R2R3, and R1, R2 and R3 are independently selected from C1-C4 alkyl, phenyl, alkyl-substituted phenyl, halogen-substituted phenyl and alkoxy-substituted phenyl; the metal compound is carbonate of sodium, potassium or cesium. According to the method for preparing silanol through silane hydrolysis, hydrogen is a unique by-product and cannot pollute the environment, and the requirement for green catalysis is met. In addition, the metal compound catalyst is low in cost, the target product silanol can be separated by extracting a reaction mixture, the product yield is high, operation is simple, and implementation is easy. In addition, the method is mild in reaction condition and easy for industrial application.

The application discloses a kind of high-efficiency continuous separation and purification device and process of crude adipic acid process, belong to chemical separation technical field.The process aims at solving the problems of low efficiency, discontinuity, high moisture content of product, impurities, large wastewater discharge and other problems existing in traditional segmented separation process.The core of this process is to use a set of sedimentation, filtration, washing function in one of the sedimentation filter centrifuge, and the crude adipic acid slurry is continuously and integrally processed, and low-moisture, low-impurity filter cake is directly obtained.Meanwhile, the separated mother liquor and washing water are innovatively introduced into a monobasic acid removal tower in parallel, and after removing impurities such as monobasic acid, the purified liquid is returned to the system for recycling.The application realizes the great simplification of process flow, the continuous automation of production process, the significant improvement of product quality and the internal circulation of resources, and is especially suitable for large-scale industrial application of adipic acid production.

The application discloses an application of a beta-cyclodextrin polymer and a grey water scale inhibition dispersant compound, and the compound comprises the following components and has the following weight ratio in terms of solid content: 50-90% of the beta-cyclodextrin polymer, 0-50% of hydrolyzed polymaleic anhydride, 0-50% of polyepoxysuccinic acid sodium and 0-50% of polyaspartic acid. The application is used for coal gasification grey water scale inhibition dispersant, and the mechanism is that the beta-cyclodextrin polymer performs grey water scale inhibition through inclusion, chelation and lattice inhibition of metal ions. The grey water scale inhibition dispersant compound of the application contains the beta-cyclodextrin polymer, and the beta-cyclodextrin polymer is used in combination with the hydrolyzed polymaleic anhydride, the polyepoxysuccinic acid sodium or the polyaspartic acid. Since the combined materials are all amphiphilic molecules with hydrophilic parts and hydrophobic parts, a variety of supramolecular aggregation systems, namely a self-assembly system of the "supramolecular cyclodextrin amphiphilic molecule", are formed, and the beta-cyclodextrin polymer can better play the scale inhibition role.
