Abstract
The utility model discloses a hollow octagonal star-shaped catalyst for synthesizing doripenem. The hollow octagonal catalyst is octagonal columnar particle, each octagonal star-shaped columnar particle is provided with 29 cylindrical through holes along the axial direction, and the outer wall of each octagonal star-shaped columnar particle is provided with eight axial open grooves; the length of the cylindrical through holes is 1.5 times the diameter of the octagonal star-shaped columnar cross section. The hollow octagonal star-shaped catalyst provided by the utility model has good hardness, is suitable for chemical industry production synthesis requiring high mechanical strength and cannot be broken easily; multiple inner through holes and external axial triangle open grooves can increase the superficial area and void ratio of the catalyst, which is favorable for hydrogenation removal of middle group and later filtration treatment in the productive process of doripenem; active components of the catalyst can be load in the inner through holes and hardly fall off due to arrangement of the alveolate 29 through holes inside, and the circulation utilization rate of the catalyst is increased.
Description
Technical field
The utility model belongs to catalyst technical field, is specifically related to a kind of for the synthetic hollow anistree star-shaped catalyst of donipenem.
Background technology
As everyone knows, the performance of catalyst and its moulding have close relationship, and when the shape of procatalyst has granular, sheet, spherical and other are irregularly shaped, the catalyst of the shape that these are different plays effective catalytic action to the fine chemical product synthetic reaction, but, the catalyst shape of the prior art part that still comes with some shortcomings in course of reaction, as granular catalyst gas communication resistance inequality, and granule is difficult to recycle; Sheet catalyst hardness is inadequate; Although spherical catalyst filling is even, fluid resistance is evenly stablized,, surface area and voidage are limited, make catalyst utilization not high.Particularly in the production of donipenem is synthetic, there is at present the deficiency that the slow and catalyst of filtering velocity can't recycled for multiple times.
Summary of the invention
The purpose of this utility model is to provide a kind of for the synthetic hollow anistree star-shaped catalyst of donipenem.
Technical solution of the present utility model: a kind of for the synthetic hollow anistree star-shaped catalyst of donipenem, described catalyst is anistree star cylindrical particle, and each anistree star cylindrical particle has 29 cylindrical holes vertically, and outer wall has eight shaft orientation opening grooves; The length of described cylindrical hole equals 1.5 times of hollow anistree star cylindrical cross-section diameter.
The diameter of described cylindrical hole equals 1/15 times of the long-diagonal of anistree star; Two length of sides of described each open slot equate, and are 135 degree angles.
The utility model compared with prior art has the characteristics that hardness is good, filtering velocity is fast and cyclic utilization rate is high.
The accompanying drawing explanation
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure side view.
The specific embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
A kind of described catalyst is anistree star cylindrical particle for the synthetic hollow anistree star-shaped catalyst of donipenem, and each anistree star cylindrical particle has 29 cylindrical holes 1 vertically, and outer wall has eight shaft orientation opening grooves 2; The length of described cylindrical hole 1 equals 1.5 times of hollow anistree star cylindrical cross-section diameter.
The diameter of described cylindrical hole 1 equals 1/15 times of the long-diagonal of anistree star; Two length of sides of described each open slot 2 equate, and are 135 degree angles.
The utlity model has good hardness, be applicable to the Chemical Manufacture that mechanical strength is high synthetic, be difficult for broken; Inner many through holes and external shaft, to the triangle open mouth groove, have increased surface area and the voidage of catalyst, are beneficial in the production process of donipenem group and later stage filtration treatment in the middle of hydrogenation and removing; Especially inner cellular 29 groups of through holes can make the catalyst activity component be carried on interior bone, and difficult drop-off increases the catalyst recycling rate.
