Embodiment 1
[0031] A composite material, comprising compound I, prepared as follows:
[0032] Add 1 mol of chloromethyltriethoxysilane and 1 mol of triethylamine into a four-necked flask equipped with a reflux device, a thermometer, and a dropping funnel, start a strong stirrer, and drop 1 mol of 6-[ (2-Amino-2-methylpropyl)amino]-N,N-dimethyl-3-pyridinecarboxamide, gradually warming up to 75°C, reflux reaction for 6h; removing the precipitated amine salt by suction filtration, and decompressing the filtrate Purify by distillation to obtain compound I; the whole reaction process is under nitrogen protection and strictly waterproof. Compound I structural formula is:
[0033]
[0034] A preparation of a high light transmittance test tube comprises the following steps:
[0035] Step 1: Pretreatment of the surface of the sample tube. First, the commercially available sample tubes are sequentially cleaned to remove oil and organic impurities;
[0036] Step 2: Preparation of hybrid silica...
Embodiment 2
[0040] The difference between the preparation of a composite material and Example 1 is: chloromethyltriethoxysilane, triethylamine and 6-[(2-amino-2-methylpropyl)amino]-N,N - The molar ratio of dimethyl-3-pyridinecarboxamide is 1:1.08:0.99.
[0041] The difference between the preparation of a high light transmittance test tube and Example 1 is:
[0042] The mass ratio of absolute ethanol, MTES, composite material, HCl, and deionized water in process 3 is 15.8:1.34:1:0.14:0.84;
[0043] The mass ratio of hybrid silica sol, silicone oligomer and absolute ethanol in step 4 is 1:0.11:4.7.
Embodiment 3
[0045] A composite material, comprising compound II, prepared as follows:
[0046] Add 1 mol of chloromethyltriethoxysilane and 1 mol of triethylamine into a four-necked flask equipped with a reflux device, a thermometer and a dropping funnel, start a strong stirrer, and drop 1 mol of 2-amino -N-(2-(2,5-dimethoxyphenyl)-2-hydroxyethyl)acetamide, gradually warming up to 75°C, reflux reaction for 6h; suction filtration to remove the amine salt precipitate, the filtrate was distilled under reduced pressure Purify to obtain compound II; the whole reaction process is protected by nitrogen and strictly waterproofed. The structural formula of compound II is as follows:
[0047]
[0048] The difference between the preparation of a test tube with high light transmittance and that of Example 1 is that the composite material in step 3 is the composite material prepared in this example.
