Problems solved by technology

However, this fluoroalkylsilane is prone to self-polymerization, and there is a problem of poor storage stability, and the yield of the silica nanoparticles with fluoroalkylsilane groups is not good.
Furthermore, since the silica nanoparticles with fluoroalkylsilane groups contain fluorine, they are harmful to the human body and are unfavorable for being applied to medical supplies, cosmetics or skin care products.

Embodiment 1

[0034] Embodiment 1 (C 8 h 17 O)((C 8 h 17 ) 2 N)-Tz-Si(OEt) 3

[0035] Step a: Place a 100 mL single-necked reaction flask containing 30 mL of dry dichloromethane in an ice-water bath at 0°C. 1.84 grams (10 mmol) of cyanuric chloride was added to the reaction flask, and the cyanuric chloride was dissolved. Then, 2.41 g (10 mmol) of dioctylamine was slowly dropped into the reaction flask. After reacting for 10 minutes, 1.01 g (10 mmol) of triethylamine was slowly added. After reacting for 20 minutes, 30 mL of 0.5 M aqueous sodium hydroxide solution was used for extraction twice, and the organic layer was collected. Add 50 mL of clear water to the organic layer for extraction treatment, and collect the organic layer again. Next, adding anhydrous magnesium sulfate to the organic layer to remove water, and then filtering to obtain a filtrate. Dichloromethane in the filtrate was removed using a vacuum concentrator to obtain 3.69 g (9.5 mmol) of 2,4-dichloro-6-dioctylamin...

Embodiment 2

[0039] Embodiment 2 (C 2 h 5 O)((C 8 h 17 ) 2 N)-Tz-Si(OEt) 3

[0040] The difference between this Example 2 and this Example 1 is that the 1-octanol in step b of Example 1 is replaced by ethanol, and the compound formed after step b is completed is 2-chloro-4-dioctylamino -6-Ethyloxy-1,3,5-triazine. And replace 2-chloro-4-dioctylamino-6-octyloxy-1,3,5-triazine in step c with 2-chloro-4-dioctylamino-6-ethane oxy-1,3,5-triazine, and the compound formed after completion of step c is 2-dioctylamino-4-ethyloxy-6-(3-triethoxysilylpropyl ) amino-1,3,5-triazine. The overall yield for this Example 2 was 47.0%.

Embodiment 3

[0042] Embodiment 3 ((CH 3 ) 2 CHO)((C 8 h 17 ) 2 N)-Tz-Si(OEt) 3

[0043] The difference between this Example 3 and this Example 1 is that the 1-octanol in step b of Example 1 is replaced with isopropanol, and the compound formed after step b is completed is 2-chloro-4-dioctyl Amino-6-isopropyloxy-1,3,5-triazine. And replace 2-chloro-4-dioctylamino-6-octyloxy-1,3,5-triazine in step c with 2-chloro-4-dioctylamino-6-iso Propyloxy-1,3,5-triazine, while the compound formed after completion of step c is 2-dioctylamino-4-isopropyloxy-6-(3-triethoxysilyl Propyl)amino-1,3,5-triazine. The overall yield for this Example 3 was 38.3%.

Abstract

A triazine-based precursor, a method for preparing a triazine-based precursor, and an application of the triazine-based precursor, the triazine-based precursor is represented by formula (I): X and Y are each selected from ‑NR 1 R 2 ,-OR 3 or-SR 4 ; 1 selected from hydrogen, unsubstituted C 1 to C 22 straight-chain alkyl, or unsubstituted C 1 to C 22 branched chain alkyl; R 2 , R 3 and R 4 each selected from unsubstituted C 1 to C 22 Straight-chain alkyl, unsubstituted C 1 to C 22 and Z represents ‑NH‑R 5 ‑Si(OR 6 ) 3 , R 5 means C 2 to C 4 The alkylene group, and each R 6 Respectively represent C 1 to C 2 of alkyl. The invention also provides a method for preparing silica micron composite particles, and a silica micron composite particle. Since the silicon dioxide micro-composite particles are non-toxic to cells and non-irritating to the skin, they can be used in medical supplies, health care supplies or daily necessities.
