Abstract
The invention discloses a preparation technology of BPEF (4, 4'-(9-fluorenylidene) bis (2-phenoxy-ethanol)) with high bulk density. Powdery BPEF is subjected to dry powder tableting by a hydraulic machine or granulation by a roller dry-technique granulator or fusing granulation to prepare a space structure of BPEF with the high bulk density, wherein powdery BPEF is subjected to dry powder tableting by the hydraulic machine and is directly compressed into cylindrical, square and half-moon-shaped space structures; the powdery BPEF is directly compressed into ingot-shaped, grain-shaped and strip-shaped space structures by the roller dry-technique granulator; and the fusing granulation comprises the steps as follows: the BPEF is heated to be in a fusing state, then the BPEF in the fusing state is uniformly distributed on a steel belt of a rotation belt type condensation granulator, is cooled in a continuous spraying manner, and finally is used for producing hemispherical, strip-shaped and sheet-shaped space structures with the forms of intermittent dipping, continuous strip discharging and full-width cloth overflowing. The technology is simple and convenient, and can effectively increase bulk density and fluidity of BPEF, so that not only is the production efficiency improved, but also the environment pollution is prevented.
Description
Technical field
The present invention relates to the preparation technology of a kind of high-bulk-density BPEF.
Background technology
The BPEF name is called 9,9-two [(4-(2-hydroxy ethoxy) phenyl] fluorenes cas:117344-32-8, and BPEF is because the difference of product crystalline form has high-bulk-density (greater than 0.5g/cm
3) and low bulk density (less than 0.5g/cm
3) branch.Compare with the high-bulk-density product, there is following problem in the BPEF of low bulk density in the industrialization use.
1) because its bulk density is low, when using this " light material " BPEF, directly cause production efficiency to reduce.For example: onesize reactor, if high-bulk-density (supposes that high-bulk-density is 0.7g/cm
3) BPEF can throw 700 kilograms, and low bulk density (supposes that low bulk density is 0.4g/cm
3) BPEF can only throw 400 kilograms, so directly cause production efficiency to reduce about 42%.
2) BPEF of low bulk density BPEF and high-bulk-density compares, and the flowability of low bulk density BPEF is poor.Because it is mobile poor, when using the BPEF of this low bulk density, BPEF easily is bonded on equipment or the packing, and easily waves in operating environment, causes environmental pollution.
Summary of the invention
The present invention is directed to above-mentioned deficiency, researched and developed the preparation technology of a kind of high-bulk-density BPEF, purpose is: this technology improves its bulk density by the profile that changes BPEF, and has improved its flowability, not only improve production efficiency, and avoided environmental pollution.
Technical solution of the present invention: the preparation technology of a kind of high-bulk-density BPEF is characterized in that: the stereochemical structure that powdery BPEF is prepared into high-bulk-density BPEF by the mode of hydraulic press dry powder sheeting or pair roller non-slurry pelletizing machine granulation or melt pelletization.
Described hydraulic press dry powder sheeting mode adopts four post molten stainless steel press, frame hydraulic press, flower basket type one-shot hydraulic press, rotary pelleting machine.
The pressure limit of described four post molten stainless steel press is 8～500 tons.
The extruding force scope of described pair roller non-slurry pelletizing machine granulation is 4MPa-18MPa.
The employed comminutor of described melt pelletization mode is revolution belt condensation comminutor.
Described powdery BPEF directly is pressed into column type, square, half-moon-shaped stereochemical structure by the hydraulic press dry powder sheeting.
Described powdery BPEF directly is pressed into ingot shape, grain type, stripe shape stereochemical structure by pair roller non-slurry pelletizing machine.
Described melt pelletization mode step is: earlier BPEF is heated to molten condition; BPEF with molten condition is evenly distributed on the steel band of revolution belt condensation comminutor then; mode by continuous spray is cooled off, and selects at last intermittently to drip, shaping and full duration overflow cloth form are produced hemispherical, strip and sheet stereochemical structure respectively continuously.
Described high-bulk-density BPEF stereochemical structure is carried out break process.
Beneficial effect of the present invention: this technology is simple and convenient, can effectively improve bulk density and the flowability of BPEF, has not only improved production efficiency, and has avoided environmental pollution.
