681-98-1 Usage
General Description
Titanium(IV) isobutoxide is a chemical compound with the formula Ti[OCH(CH3)2]4. It is a colorless-to-pale-yellow liquid with a strong odor, and is used as a precursor in the synthesis of titanium-based materials, such as titanium dioxide and titanium alkoxides. It is highly reactive and flammable, and should be handled with caution. Titanium(IV) isobutoxide is also used as a catalyst in organic synthesis, and as a cross-linking agent in the production of polymers. It is an important industrial chemical with applications in the production of coatings, adhesives, and other materials where its unique properties as a titanium compound are beneficial.
Check Digit Verification of cas no
The CAS Registry Mumber 681-98-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 681-98:
(5*6)+(4*8)+(3*1)+(2*9)+(1*8)=91
91 % 10 = 1
So 681-98-1 is a valid CAS Registry Number.

Reaction of silicon with alcohols in autoclave
Krylova,Egorov,Nefedov
, p. 260 - 266 (2017/07/11)
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.
