Abstract
The invention provides a process system for preparing tenofovir disoproxil fumarate. The process system is characterized by comprising a filtering device (1), wherein the filtering device (1) comprises a dish-shaped body (2) and a pyramidal body (3), wherein an opening (4) is formed in one end of the dish-shaped body (2) and is matched with the inner side of an opening of the pyramidal body (3). The process system is low in cost, high in filtering efficiency, and suitable for pharmaceutical and chemical processes.
Description
Technical field
The present invention relates to a kind of chemical reaction equipment, be specifically related to one and prepare tenofovir disoproxil fumarate process unit.
Background technology
Tenofovir disoproxil fumarate, its chemistry is by name: 9-((R)-2-((two (((isopropoxy carbonyl) oxygen base (methoxyl group) phosphinyl)-propyl group) adenine fumarate (1:1), be applicable to other antiretroviral drugs share, treatment HIV-1 infects.Preparing in tenofovir disoproxil fumarate process, relating to filtration link, because the coefficient of viscosity of different liquids is different, selecting different filters, increase cost.
Summary of the invention
In order to solve the problem, one is the object of the present invention is to provide to prepare tenofovir disoproxil fumarate multifunction craft device.
One provided by the invention prepares tenofovir disoproxil fumarate process unit technical scheme:
One prepares tenofovir disoproxil fumarate process system, comprises filter, and this filter comprises plakea, cone, and there is interface one end of described plakea, this interface and described pyramidal opening inner side suitable.
As preferably, described interface has screw thread, and described pyramidal opening inner side has suitable screw thread.
As preferably, described plakea has interlayer, this interlayer is provided with aperture, the interlayer of replaceable different small aperture on described plakea.
As preferably, described plakea can be suitable from the cone of different tapering.
Advantageous Effects of the present invention:
The present invention adopts split type filter, and plakea according to the viscosity of medium, can select the cone of suitable different taperings, and the interlayer of replaceable suitable small aperture, filters, both reduces cost, raise the efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is the outside schematic diagram of invention;
In Fig. 2, a1 is that interface has screw thread schematic diagram; B1 is that cone opening inner side has screw thread schematic diagram;
In Fig. 3, a2 is that interface is without screw thread schematic diagram; B2 is that cone opening inner side is without screw thread schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.
Embodiment 1
As shown in Figure 1, 2, 3, one prepares tenofovir disoproxil fumarate process system, comprises filter 1, and this filter 1 comprises plakea 2, cone 3, there is interface 4 one end of described plakea 2, and this interface 4 is suitable with the opening inner side of described cone 3.
In the present embodiment, described interface 4 has screw thread, and the opening inner side of described cone 3 has suitable screw thread; And described plakea (2) has interlayer, this interlayer is provided with aperture, the interlayer of the upper replaceable different small aperture of described plakea (2).In filtering, described plakea 2 can be suitable from the cone 3 of different tapering.
The present invention adopts split type filter, and plakea according to the viscosity of medium, can select the cone of suitable different taperings, and the interlayer of replaceable suitable small aperture, filters, both reduces cost, raise the efficiency simultaneously.
Present specification describes some embodiments, but should be understood that those skilled in the art pass through to read this description and can know the various improvement not deviating from the spirit and scope of the present invention.Therefore, these other embodiments also should be included within the scope of appended claims.
