2. Tetrabutylphosphonium Hydroxide is a phase transfer catalyst for the etherification of thiosalicylic acid and analogs. Tetrabutylphosphonium Hydroxide is a pretreatment for rice husks that enhances enzymic and acid hydrolysis yields. Tetrabutylphosphonium Hydroxide is used in the synthesis of tetrabutylphosphonium carboxylate as a recyclable and highly selective catalysts for alcoholysis reaction of propylene oxide.
Check Digit Verification of cas no
The CAS Registry Mumber 14518-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,1 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14518-69:
(7*1)+(6*4)+(5*5)+(4*1)+(3*8)+(2*6)+(1*9)=105
105 % 10 = 5
So 14518-69-5 is a valid CAS Registry Number.

The efficient and environmentally benign epoxidation of allylic alcohols has been attained by using new kinds of monomeric peroxotantalate anion-functionalized ionic liquids (ILs=[P4,4,4,n]3[Ta(O)3(η-O2)], P4,4,4,n=quaternary phosphonium cation, n=4, 8, and 14), which have been developed and their structures determined accordingly. This work revealed the parent anions of the ILs underwent structural transformation in the presence of H2O2. The formed active species exhibited excellent catalytic activity, with a turnover frequency for [P4,4,4,4]3[Ta(O)3(η-O2)] of up to 285 h?1, and satisfactory recyclability in the epoxidation of various allylic alcohols under very mild conditions by using only one equivalent of hydrogen peroxide as an oxidant. NMR studies showed the reaction was facilitated through a hydrogen-bonding mechanism, in which the peroxo group (O–O) of the peroxotantalate anion served as the hydrogen-bond acceptor and hydroxyl group in the allylic alcohols served as the hydrogen-bond donor. This work demonstrates that simple monomeric peroxotantalates can catalyze epoxidation of allylic alcohols efficiently.
