Description
Trimethoxypropylsilane, also known as Propyltrimethoxysilane, is an alkylalkoxysilane that exists as a colorless, low viscosity liquid. It consists of an n-propyl organic group and a trimethoxysilyl inorganic group, which together provide a hydrophobic surface treatment. This versatile compound is widely utilized in various industries due to its unique properties and applications.
Uses
Trimethoxypropylsilane is used as a key material in sol-gel production, where it adds moderate organic properties to the silicone mesh, similar to the propyl group in the product. The presence of propyl groups also enhances the organic properties of the product.
Used in Sol-Gel Production:
Trimethoxypropylsilane is used as an important material in sol-gel production for providing a hydrophobic surface treatment to inorganic powders or filler materials. This application is crucial in creating materials with tailored properties for various industries.
Used in Polyolefin Production:
Trimethoxypropylsilane serves as one of the catalyst components for polyolefin production using Ziegler-Natta catalysts. Its role in this process is essential for the efficient and effective production of polyolefins.
Used in Silicone Sealant Formulations:
Trimethoxypropylsilane is used as a neutral curing agent in silicone sealant formulations. It is primarily utilized for crosslinking α,ω-silanol polydimethylsiloxanes in the presence of atmospheric moisture. This silane is often the main crosslinker of choice for oxime silicone sealants and can be used alone or in combination with other oxime silanes to achieve targeted properties, such as desired cure rate and adhesion.
Chemical Properties:
Trimethoxypropylsilane is a colorless or yellowish clear liquid with unique chemical properties that make it suitable for a wide range of applications. Its ability to react faster with water than other similar compounds allows customers to regulate the rate of hydrolysis according to their specific application needs.

Check Digit Verification of cas no
The CAS Registry Mumber 1067-25-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1067-25:
(6*1)+(5*0)+(4*6)+(3*7)+(2*2)+(1*5)=60
60 % 10 = 0
So 1067-25-0 is a valid CAS Registry Number.

Synthetic method of linear dihydric alcohol
-
Paragraph 0104-0106; 0125-0130, (2021/09/01)
The invention discloses a synthetic method of linear dihydric alcohol. The synthetic method comprises the following steps: (1) carrying out hydrosilylation reaction on alpha-olefin and siloxane to obtain alkyl siloxane; (2) carrying out hydroxymethylation reaction on alkyl siloxane, organic metal alkali and a hydrogen acceptor to obtain silyl alcohol; and (3) carrying out oxidation reaction on the silyl alcohol, fluorine-containing metal salt and peroxide to obtain the linear dihydric alcohol. The method has the advantages of mild process, easily available raw material sources, no need of post-treatment after the reaction is completed, capability of being directly used for the next reaction, simplification of the process flow, high conversion rate, high selectivity, low cost and suitability for large-scale production.
COSMETIC TREATMENT METHOD COMPRISING THE APPLICATION OF A COATING BASED ON AN AEROGEL COMPOSITION OF LOW BULK DENSITY
-
Paragraph 0067, (2014/02/15)
The present invention relates to a cosmetic treatment method comprising the formation of a coating on keratin fibres characterized in that it comprises: 1) the preparation of an aerogel precursor composition comprising:—at least one organic solvent chosen from acetone, C1-C4 alcohols, C1-C6 alkanes, C1-C4 ethers, which may or may not be perfluorinated, and mixtures thereof and at least one precursor compound that contains:—at least one atom chosen from silicon, titanium, aluminium and zirconium,—at least one hydroxyl or alkoxy function directly attached to the atom chosen from silicon, titanium, aluminium and zirconium by an oxygen atom, and,—optionally an organic group directly attached to the atom chosen from silicon, titanium, aluminium and zirconium by a carbon atom, 2) the removal of the solvent or solvents resulting in the formation of an aerogel composition having a bulk density less than or equal to 0.35 g/cm3, 3) the application to the keratin fibres of the aerogel composition resulting from step 2) or of the aerogel precursor composition resulting from step 1). Advantageously, the molar ratio between the precursor compounds and the solvent is at most 1/20.
