Embodiment 1

[0029] Step 1). Commercially available zirconium nitrate (Zr(NO 3 ) 4 ·5H 2 O) be dissolved in water as a pillar liquid, and the mass percent concentration of zirconium nitrate is 35%.

[0030] Step 2). Add white clay to water, the mass percentage of white clay and water is 1:2, stir until the white clay is dispersed in water, add FC-006 perfluoroalkyl betaine with 3% white clay mass, the structural formula is C 8 f 17 SO 2 NHCH 2 CH 2 CH 2 N + (CH 3 ) 2 CH 2 COO - , the perfluoroalkyl betaine product comes from Wuhan Changjiang Fluorine Technology Co., Ltd., continue to stir to obtain a clay solution.

[0031] Step 3). Mix the pillar liquid obtained in step 1) with the clay solution obtained in step 2), so that zirconium nitrate accounts for 8% of the clay mass, stir at 90°C for 50h, then centrifuge, wash, granulate, and dry , roasting and other processes to obtain a nonylphenol modified clay catalyst product numbered KRB-1, by mass percentage, KRB-1 component co...

Embodiment 2

[0033] The amount of the perfluoroalkyl betaine added in step 2 is changed to account for 1% of the clay mass, and the others are the same as in Example 1. The resulting product number is KRB-2.

Embodiment 3

[0035] The amount of the perfluoroalkyl betaine added in the step 2 is changed into 5% of the clay mass, and the others are the same as in Example 1. The resulting product number was KRB-3.

Abstract

The invention provides a carclazyte catalyst for preparing nonyl phenol. The carclazyte catalyst comprises the following components by weight percent: 85% to 95% of carclazyte, 1% to 5% of perfluorinated alkyl betaine and 1% to 10% of zirconium nitrate, wherein the molecular formula of the perfluorinated alkyl betaine is C15H15F17N2O4S; the structural formula of the perfluorinated alkyl betaine is C8F17SO2NHCH2CH2CH2N<+> (CH3)2CH2COO<->. Compared with the common carclazyte catalyst, the unit consumption of the carclazyte catalyst provided by the invention is decreased by more than 5 times, so that the service life of the catalyst is prolonged and the activity of the catalyst is certainly improved. The invention further provides a preparation method of the carclazyte catalyst. The method is short in technological process, moderate in reaction condition and low in energy consumption, and has an industrial popularization value.

Description

technical field [0001] The invention relates to a clay catalyst, in particular to a clay catalyst for preparing nonylphenol, and a preparation method thereof. Background technique [0002] Nonylphenol is an important fine chemical raw material and intermediate. It is a colorless or light yellow liquid at room temperature with a slight phenol smell. It is insoluble in water but soluble in acetone. Mainly used in the production of surfactants, but also in antioxidants, textile printing and dyeing auxiliaries, lubricating oil additives, pesticide emulsifiers, resin modifiers, resin and rubber stabilizers and other fields. Nonylphenol can cause feminization of male fish downstream of sewage treatment plants, and is an endocrine disruptor or environmental hormone organic compound with estrogenic effects. [0003] For the reaction of nonene and phenol, the catalysts mainly used abroad are activated clay and cation exchange resin. According to reports, sulfuric acid-treated zirco...
