Description
3-Mercaptopropylmethyldimethoxysilane is a bifunctional organosilane that possesses a reactive organic mercapto group and a hydrolyzable inorganic methoxysilyl group. It is a clear, colorless to light yellow liquid with a slightly mercaptan odor and is soluble in alcohols, ketones, and aliphatic or aromatic hydrocarbons.
Uses
Used in Adhesive Industry:
3-Mercaptopropylmethyldimethoxysilane is used as a coupling agent to improve the adhesion of sulfur-cured elastomers (such as polysulfide and polyurethane sealants) to inorganic fillers (e.g., silica, clay, glass, mica, and talc), fiberglass, and surfaces.
Used in Rubber and Tire Industry:
3-Mercaptopropylmethyldimethoxysilane is used to enhance the properties of mineral-filled elastomers, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set, and cure time. It is also used to improve low-rolling resistance in silica-reinforced tire tread compounds.
Used in Sol-Gel Synthesis:
3-Mercaptopropylmethyldimethoxysilane is used as a silane precursor in the synthesis of Nafion-MPMDMS nanocomposite membranes by the sol-gel method.
Used in Heavy Metal Ions Adsorption:
3-Mercaptopropylmethyldimethoxysilane is used to functionalize magnetic-polysilsesquioxane (PSSQ) nanoparticles, making them applicable for heavy metal ions adsorption.
Used in Nanoparticle Synthesis:
3-Mercaptopropylmethyldimethoxysilane is used in the synthesis of thiol-organosilica nanoparticles.
Used in UV Laminated Adhesive Preparation:
3-Mercaptopropylmethyldimethoxysilane can be used to prepare UV laminated adhesives.

Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 31001-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,0 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31001-77:
(7*3)+(6*1)+(5*0)+(4*0)+(3*1)+(2*7)+(1*7)=51
51 % 10 = 1
So 31001-77-1 is a valid CAS Registry Number.

Paragraph 0029-0031, (2020/09/30)
The invention relates to a method for preparing mercaptosilane in virtue of a thiourea process, belonging to the technical field of fine chemical engineering. The method comprises the following steps:dropwise adding an alcoholic solution of thiourea into chloropropyl siloxy silane and dodecyl trimethyl phosphorus bromide, carrying out a condensation reaction and an aging reaction, and conductingstanding for layering to obtain a mercaptosilane product. According to the invention, an isomerization reaction is inhibited by adjusting reaction conditions; the consumption of thiourea is reduced; ethylenediamine is used as a neutralization initiator, so solid by-products can be greatly reduced; and a guanidine salt state can be changed, so a crude product and a salt can be better separated, operation is simplified, and yield is improved.

To provide an epoxide-production-use catalyst that is suitably used for producing an epoxide by partial oxidation of an unsaturated hydrocarbon, a catalyst in accordance with the present invention is obtained by fixing gold fine particles to a carrier containing an oxide containing at least one of titanium and zirconium, and has an acid quantity of not more than 0.1 mmol/g determined by the NH3-TPD method. Such a catalyst for epoxide producing use can be produced by, for instance, fixing gold fine particles to a carrier having an acid quantity of not more than 0.15 mmol/g. The catalyst for epoxide producing use arranged as above is preferably used as a catalyst in partial oxidation of an unsaturated hydrocarbon to produce a corresponding epoxide.
