specific Embodiment approach 1

[0025] Specific implementation mode one: combine figure 1 A method for measuring the hydrophilicity and hydrophobicity of bisphenol compounds in this embodiment is specifically prepared according to the following steps:

[0026] Step 1. Before XAD8 resin and XAD4 resin are loaded into the resin column, the XAD8 resin or XAD4 resin needs to be purified; XAD8 resin and XAD4 resin are respectively soaked in 0.1-0.2mol / L sodium hydroxide for 1 day, and the soaked The XAD8 resin and XAD4 resin were purified by Soxhlet extractor for 20-26 hours, and the purified XAD8 resin and XAD4 resin were stored in pure methanol respectively;

[0027] Step 2. Before loading the resin column, clean the XAD8, XAD4 resin and the resin column; respectively put the XAD8 resin and XAD4 resin stored in pure methanol in step 1 into a 1L beaker, add 600-800mL of ultrapure water, and stir for 2 After ~4min of static settling, discard the supernatant; wash repeatedly for 7-10 times; obtain the cleaned XAD...

specific Embodiment approach 2

[0044] Embodiment 2: This embodiment differs from Embodiment 1 in that the concentration of sodium hydroxide in step 1 is 0.125-0.175 mol / L. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0045] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the soaked XAD8 resin and XAD4 resin in step 1 are purified by Soxhlet extractor for 21-25 hours. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a method for determining the hydrophilic-hydrophobic properties of bisphenol compounds, and aims at solving the problems that operation is complex, the consumed time is long, n-caprylic alcohol has the stimulatory effect on the eyes, the skin, the mucosas and the upper respiratory tracts, and body injuries are prone to be caused by the n-caprylic alcohol to operating personnel. The method is implemented through the steps that 1, purified XAD8 resin and XAD4 resin are preserved in pure methanol; 2, the washed XAD4 resin and XAD8 resin are obtained; 3, a first resin column and a second resin column are obtained; 4, the first resin column and the second resin column are each alternately washed for 3 times by a NaOH solution and a HCl solution through a peristaltic pump; 5, hydrophilic organic matter is collected; 6, hydrophobic organic matter is collected; 7, neutral organic matter is collected; 8, an enrichment solution is obtained; 9, the hydrophilic property or hydrophobic property of the eight bisphenol compounds in the enrichment solution is judged. The method is applied to the field of determination of the hydrophilic-hydrophobic properties of the bisphenol compounds.

Description

technical field [0001] The invention relates to a method for the hydrophilicity and hydrophobicity of compounds, in particular to a method for measuring the hydrophilicity and hydrophobicity of bisphenol compounds. Background technique [0002] Bisphenols are a class of fine chemicals with similar chemical structures, generally referring to a class of substances with two hydroxyphenyl structures. According to the different substituents on the hydroxyphenyl group and the carbon bridge, it can be divided into different analogues. The most common ones are bisphenol A (BPA), bisphenol AF (BPAF), bisphenol S (BPS), bisphenol F (BPF), bisphenol B (BPB), tetrachlorobisphenol A (TBBPA) and tetrachlorobisphenol A (TBBPA) Bromobisphenol A (TBBPA). Industrially, these substances are widely used due to their low cost. However, since this kind of compound belongs to environmental estrogen, it has potential endocrine disrupting effect and toxic effect on human body, and is not easy to ...
