Embodiment 1

[0029] Example 1: A light color C 5 C 9 Copolymerization resin catalyst: including the following raw materials in mass percentage: ALCL 3 20%, BF 3 Diethyl ether complex 50%, 1,2-dichloroethane 20%, diisopropyl ether 10%.

[0030] a light color C 5 / C 9 The preparation method of copolymer resin comprises the steps:

[0031] (1) Polymerization reaction: the C 5 / C 9 Mixed Raw and Light C 5 C 9 The copolymer resin catalyst is mixed in a certain proportion and added to the copolymerization reactor to generate a polymerization product under the action of the catalyst; C 5 / C 9 Mixed raw materials: The mass ratio of composite catalyst is 100:1.5; Reactor temperature: 40-45°C, Reactor pressure: 0.20-0.25MPA, Reactor feed rate: 10-10.5t / h; Reaction residence time: 3.5h ;

[0032] (2) Terminate the polymerization reaction: fully mix the product obtained in step (1) with dilute lye and add it into the termination reaction device to terminate the polymerization reaction, and...

Embodiment 2

[0043] Embodiment 2: the difference with embodiment 1 is:

[0044] a light color C 5 C 9 Copolymerization resin catalyst: including the following raw materials in mass percentage: ALCL 3 25%, BF 3 Diethyl ether complex 45%, 1,2-dichloroethane 23%, diisopropyl ether 7%.

[0045] In this polymerization reaction, by volume, 30% C 5 C 9 Copolymerization resin catalyst with 70% C 5 C 9 The composite catalyst is prepared by extracting the mixed raw materials after polymerization.

[0046] Among them, the light color C 5 C 9 The preparation method of copolymerization resin catalyst comprises the steps: BF 3 Diethyl ether complex, start the preparation kettle to stir, then add fusion agent A, fusion agent B in turn, stir for 0.5h and then use N 2 air insufflation into ALCL 3 The catalyst was prepared by continuing to stir for 1.0h.

[0047] Applied to C by the catalyst of the present invention 5 C 9 On the copolymer resin, its performance index is:

[0048] ①BF 3 The ...

Abstract

The invention discloses a light-colored C5C9 copolymer resin catalyst which comprises the following raw materials in percentage by mass: 10-35% of ALCL3, 25-55% of a BF3 diethyl ether complex, 10-25% of a fusion agent A and 5-10% of a fusion agent B. The invention aims to solve the technical problems of high energy consumption, low production yield, high catalyst consumption and high F ion content in wastewater due to the fact that a cold polymerization process in the prior art needs an ice machine for cooling.

Description

technical field [0001] The invention relates to the technical field of resin synthesis, in particular to a light-colored C 5 C 9 Copolymerization catalyst. Background technique [0002] In recent years, with the increase of demand for ethylene, domestic ethylene production facilities are developing towards large-scale development, and many sets of ethylene facilities have been added in various places in my country. For this reason, ethylene by-product C 5 and C 9 Distillate raw materials increase accordingly, for C 5 、C 9 and C 5 C 9 Copolymer resin production provides sufficient raw material resources. C 5 、C 9 and C 5 C 9 The copolymer resin market is still strong in recent years, and the resin production industry is facing huge advantages and opportunities. However, most domestic enterprises can only produce low-end C 9 and C 5 C 9 Copolymer resin, and 60-70% of it is still produced by thermal polymerization process. This kind of resin has deep color, many ...
