(Oi-bu)3SiH, also known as hydrotris(isobutoxy)silane, is a colorless liquid organosilicon compound with the chemical formula C12H29OSi. It is a silane derivative, where three isobutoxy groups (Oi-bu) are attached to a central silicon atom, and a hydrogen atom is bonded to the silicon as well. (Oi-bu)3SiH is widely used as a reducing agent in various chemical reactions, particularly in the synthesis of silanes and other organosilicon compounds. It is also employed as a coupling agent in the production of composite materials, enhancing the adhesion between inorganic and organic components. Due to its reactivity, (Oi-bu)3SiH is sensitive to moisture and air, and it is typically stored and handled under an inert atmosphere to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 3046-20-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,4 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3046-20:
(6*3)+(5*0)+(4*4)+(3*6)+(2*2)+(1*0)=56
56 % 10 = 6
So 3046-20-6 is a valid CAS Registry Number.

Reaction of silicon with alcohols in autoclave

Krylova,Egorov,Nefedov

, p. 260 - 266 (2017)

A reaction of activated silicon with alcohols in an autoclave at 240—270 °C was studied. It was found that primary alcohols form tetraalkoxysilanes Si(OR)4 with high selectivity (up to 97%), while the secondary PriOH gave a mixture of compounds HSi(OPri)3, Si(OPri)4, HSi(OPri)2OSi(OPri)2H, HSi(OPri)2OSi(OPri)3, and Si(OPri)3OSi(OPri)3 with the predominance of trialkoxysilane (up to 67%). Carrying out the reaction under the indicated conditions has the advantage of experimental simplicity, reagent availability, high conversion of silicon, good isolated yields of products.
