3102-79-2 Usage

General Description

1H,1H,2H,2H-PERFLUORODECYLMETHYLDICHLOROSILANE, also known as PFDMDS, is a chemical compound known for its hydrophobic and oleophobic surface modification applications. This chemical, due to its perfluorinated alkyl groups, is often used to increase the water and oil resistance of various substrates such as metals, glass, polymers, and ceramics. Its advanced functionality comes from the silane part of the molecule which chemically bonds with the substrate and the fluorocarbon chain, which packs tightly together to form an effective barrier to liquids. The properties of 1H,1H,2H,2H-PERFLUORODECYLMETHYLDICHLOROSILANE make it useful in a variety of industrial applications, including the manufacture of protective coatings, in water-repellent materials or easy-clean surfaces, and in the microelectronics field. However, due to its fluorinated nature, it might have potential environmental and health concerns.

Check Digit Verification of cas no

The CAS Registry Mumber 3102-79-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,0 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3102-79:
(6*3)+(5*1)+(4*0)+(3*2)+(2*7)+(1*9)=52
52 % 10 = 2
So 3102-79-2 is a valid CAS Registry Number.

Syntheses and Reaction of Metal Organics. XVII. Synthesis of Silane Coupling Agent Having Fluorocarbon Chain and Surface Modification of Glass Plate

Yoshino, Norio,Yamamoto, Yasushi,Seto, Tsuyoshi,Tominaga, Shin-ichi,Kawase, Tokuzo

, p. 472 - 476 (1993)

Four silane coupling agents, 1H,1H,2H,2H-polyfluoroalkyl(dimethoxy)(methyl)silanes (1H,1H,2H,2H-henicosafluorododecyl(dimethoxy)(methyl)silane, C10F21C2H4Si(CH3)(OCH3)2, 1H,1H,2H,2H-heptadecafluorodecyl(dimethoxy)(methyl)silane, C8F17C2H4Si(CH3)(OCH3)2, 1H,1H,2H,2H-tridecafluorooctyl(dimethoxy)(methyl)silane, C6F13C2H4Si(CH3)(OCH3)2, and 1H,1H,2H,2H-nonafluorohexyl(dimethoxy)(methyl)silane, C4F9C2H4Si(CH3)(OCH3)2), were prepared by the hydrosilylation of dichloro(methyl)silane with the corresponding 1H,1H,2H,2H-polyfluoro-1-alkene in the presence of hydrogen hexachloroplatinate(IV), followed by the reaction with sodium methoxide.The surface modification of glass plate was attempted uisng these products.From measurements of the contact angles θ(deg) of water and oleic acid against a modified glass plate surface, the coupling agents were found to have high modification ability.The oxidation resistance of the modified glass surface was also investigated.

Redistribution of dichlorosilanes and dihydridosilanes. Synthesis of chloro hydridosilanes

Benouargha,Boulahia,Boutevin,Caporiccio,Guida-Pietrasanta,Ratsimihety

, p. 79 - 87 (2007/10/03)

The redistribution of dichlorosilanes RSi(CH3)Cl2 and dihydridosilanes RSi(CH3)H2, prepared by reduction of the homologues dichlorosilanes, in the presence of a quaternary ammonium salt is presented. The influence of the nature of R (fluoroalkyl chain RFCH2CH2 with RF = CF3, C4F9, C8F17, alkyl chain R = C6H13 or aromatic R = C6H5) and of the temperature on the rate of the reaction is studied. The equilibrium constants and free enthalpies are calculated and discussed taking into account the nature of R. The new products described were characterized from I.R, 1H, 19F and 29Si NMR spectroscopies.
