Embodiment 1

[0017] Example 1 In a 100ml four-necked flask equipped with a stirrer, a thermometer, a high-efficiency reflux condenser and an extremely flexible and expandable soft seal at the top of the condenser, add 0.2mol (29.9g) of methyltrichlorosilane ,. Then add 0.6 mol (34.8 g) of propylene oxide dropwise under the liquid surface under cooling conditions, and control the temperature not to exceed 70°C at the rate of addition, and react at 70°C for 10 hours after the drop is completed. After the reaction was completed, a small amount of low-boiling matter was distilled off under reduced pressure to obtain a colorless liquid methyltris(2-chloropropoxy)silane with a product yield of 93%. Its flash point (open cup): 200±5°C, decomposition temperature: 250±5°C, density 1.273g / ml, refractive index n D 25 = 1.4486.

Embodiment 2

[0018] Example 2 Add 0.2 mol (29.9 g) of methyltrichlorosilane to a 100 ml four-neck flask equipped with a stirrer, a thermometer, a high-efficiency reflux condenser, and an extremely flexible and expandable soft seal at the top of the condenser ,. Then add 0.65 mol (37.7 g) of propylene oxide dropwise under the liquid surface under cooling conditions, and control the temperature not to exceed 70°C at the rate of addition, and react at 60°C for 8 hours after dropping. After the reaction is over, excess propylene oxide (recycled) is distilled off under normal pressure, and a small amount of low-boilers are removed by distillation under reduced pressure to obtain a colorless liquid methyl tris(2-chloropropoxy)silane with a product yield of 96%. . Its flash point (open cup): 200±5°C, decomposition temperature: 250±5°C, density 1.273g / ml, refractive index n D 25 = 1.4486.

Embodiment 3

[0019] Example 3 Add 0.2 mol (29.9 g) of methyltrichlorosilane to a 100 ml four-neck flask equipped with a stirrer, a thermometer, a high-efficiency reflux condenser tube and an extremely flexible and expandable soft seal at the top of the condenser tube ,. Then add 0.7mol (40.6g) of propylene oxide dropwise under the liquid surface under cooling conditions, and control the temperature not to exceed 50°C at the rate of addition, and react at 50°C for 6 hours after the drop is completed. After the reaction is over, excess propylene oxide (recycled) is distilled off under normal pressure, and a small amount of low-boilers are removed by distillation under reduced pressure to obtain a colorless liquid methyl tris(2-chloropropoxy)silane with a product yield of 98%. . Its flash point (open cup): 200±5°C, decomposition temperature: 250±5°C, density 1.273g / ml, refractive index n D 25 = 1.4486.

Abstract

The invention relates to a chloride-containing organic silicon inflaming retarding plasticizer methyl tri(2-chloropropyl)silane compound and a preparation method thereof. The structural of the compound is shown in the specification. The preparation method comprises the following steps: dropwise adding epoxypropane with a certain molar ratio in methyl trichlorosilane below the liquid level and then insulating for a period of time after dropwise adding; removing excess epoxypropane and few substances with low boiling points through distillation so as to obtain the colorless liquid methyl tri(2-chloropropyl)silane compound. The methyl tri(2-chloropropyl)silane compound has the advantages of good inflaming retarding plasticity, simple production process, less equipment investment and low cost. The preparation method is easy to achieve industrial production.

Description

technical field [0001] The invention relates to a methyl tris(2-chloropropoxy)silane compound and a preparation method thereof. Methyltris(2-chloropropoxy)silane is a flame-retardant plasticizer of chlorine-containing silicone, which is suitable for flame-retardant plasticizing additives of polyvinyl chloride, polyurethane, epoxy resin, unsaturated resin, etc. Background technique [0002] With the wide application of polymer materials, because of its flammability, it often causes fires and poses a serious threat to people's lives and property, thus promoting the research of flame retardant technology and the rapid development of flame retardant plasticizer industry. Flame retardant plasticizer is a plastic processing aid with flame retardant function and plasticizing effect. It can overcome the problem of making polymer materials more flammable due to the addition of plasticizers. At present, there are many studies on phosphate ester flame retardant plasticizers, and peopl...
