Specification

The 3-Chloropropyltriethoxysilane, with the CAS registry number 5089-70-3, is also known as Triethoxy(gamma-chloropropyl)silane. It belongs to the product categories of Industrial/Fine Chemicals; Chloro; Chloroalkylsilanes, etc. (Silane Coupling Agents); Functional Materials; Si (Classes of Silicon Compounds); Silane Coupling Agents; Si-O Compounds; Trialkoxysilanes; Alkoxy Silanes; Silane series; Organometallic Reagents; Organosilicon. Its EINECS registry number is 225-805-6. Its IUPAC name is called 3-chloropropyl(triethoxy)silane. The product which is colorless transparent liquid should be sealed and stored in dark, cool and dry place. What's more, it can be used for making silicone and silane coupling agent. Meanwhile, its own can also be used as a coupling agent of epoxy composite materials.

Physical properties of 3-Chloropropyltriethoxysilane: (1)ACD/LogP: 2.72; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 2.72; (4)ACD/LogD (pH 7.4): 2.72; (5)ACD/BCF (pH 5.5): 68.43; (6)ACD/BCF (pH 7.4): 68.43; (7)ACD/KOC (pH 5.5): 716.63; (8)ACD/KOC (pH 7.4): 716.63; (9)#H bond acceptors: 3; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 9; (12)Index of Refraction: 1.427; (13)Molar Refractivity: 62.54 cm³; (14)Molar Volume: 243.3 cm³; (15)Surface Tension: 25.5 dyne/cm; (16)Density: 0.989 g/cm³; (17)Flash Point: 78.8 °C; (18)Enthalpy of Vaporization: 44.85 kJ/mol; (19)Boiling Point: 230.8 °C at 760 mmHg; (20)Vapour Pressure: 0.0978 mmHg at 25°C.

Preparation: this chemical can be prepared by allyl chloride and dichloro-silane which will conduct the addition reaction, and they will conduct alcoholysis reaction with ethanol. At last, you can obtaine γ-chloropropyl triethoxysilane.

Uses of 3-Chloropropyltriethoxysilane: it can be used to produce Triethoxy-(3-iodopropyl)-silan by heating. This reaction is will need reagent NaI and solvent acetone with reaction time of 24 hours. The yield is about 58%.
