摘要： The present invention discloses the device and method for continuously preparing high-purity AKD without solvent. The adopted device includes a kind of reactor which could make continuous mixing reaction of raw materials. The main preparation process is: firstly, the tertiary amine is continuously fed into the reactor from starting end and the acyl chloride is continuously fed from three to ten line; secondly, under the operating state of reactor, the main motor drives the internal cylinder to rotate in relation to external cylinder, forcing the fed materials to be conveyed and stirred by blades in the conveying section of annular column passage and forcing the fed materials to be sheared and mixed by relative movement of shearing blades and kneading blades at mixing section. Due to alternate arrangement of conveying section and mixing section along the axial direction of annular column passage, it causes the sufficient reaction of fed materials and controls the material temperature through internal and external heat exchange systems until the reaction products are discharged continuously from outlet. The device and process adopted by the present invention could realize the disperse generation of reaction heat and sufficient material mixture and complete reaction to make it easy to control the reaction temperature and material viscosity and decrease the generation of side reaction to ensure the high purity of products.

摘要： Disclosed is a novel process for the manufacture of 2,2,4,4-tetramethylcyclobutane-1,3-diol commencing with the pyrolysis of isobutyric anhydride to produce dimethylketene. Dimethylketene is absorbed into 2,2,4,4-tetramethylcyclobutane-1,3-dione which function as the process solvents for subsequent dimerization of the dimethylketene to 2,2,4,4-tetramethylcyclobutane-1,3-dione followed by the catalytic hydrogenation of the dione to the diol product.

摘要： A method of co-producing acetic anhydride and an acetate ester includes pyrolizing acetic acid at elevated temperature to produce a first ketene stream, the first ketene stream being a vapor phase stream comprising ketene, acetic acid and water; cooling the first ketene stream to condense acetic acid and water therefrom, thereby generating (i) a weak acid aqueous stream and (ii) a ketene feed stream; feeding the ketene feed stream to an acetic anhydride reactor where the ketene is reacted with acetic acid to produce acetic anhydride; concurrently with step (c ), feeding the weak acid aqueous stream to an esterification reactor wherein acetic acid in the weak acid stream is reacted with an organic alcohol to produce an acetate ester. Preferably, the organic alcohol is selected from organic alcohols which (i) form acetate esters which esters and optionally alcohols provide azeotropic mixtures with water and (ii) wherein the azeotropic mixtures have a water content greater than the amount of water generated by reaction of the alcohol with acetic acid to facilitate azeotropically separating the acetate ester from the reaction mixture.
