Chemical Properties

white powder

Uses

Different sources of media describe the Uses of 32503-27-8 differently. You can refer to the following data:
1. Displays antibacterial properties due to the presence of the quaternary amine and the counter ion.
2. A compound that displays antibacterial properties
3. Phase transfer catalyst Tetra-n-butylammonium hydrogen sulfate shows antibacterial properties due to the presence of the quaternary amine and the counter ion. It serves as a phase-transfer catalyst, surface-active agent, solvent, intermediate, active ingredient for conditioners, antistatic agent, detergent sanitizers, softener for textiles and paper products, emulsifying agents and pigment dispersers. It is used as an efficient catalyst in the N-alkylation reactions of benzanilides, cyclization of beta-amino acids to beta-lactams, conversion of nitriles to amides, dehydrohalogenation of aryl 2-haloethyl ethers to give vinyl ethers and in the oxidation of alcohols.

General Description

Tetrabutylammonium bisulfate, a quaternary ammonium salt, is a phase-transfer reagent.

Purification Methods

The sulfate crystallises from acetone. It has been used as a phase transfer catalyst.

Check Digit Verification of cas no

The CAS Registry Mumber 32503-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,0 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 32503-27:
(7*3)+(6*2)+(5*5)+(4*0)+(3*3)+(2*2)+(1*7)=78
78 % 10 = 8
So 32503-27-8 is a valid CAS Registry Number.

Role of Organic Fluoride Salts in Stabilizing Niobium Oxo-Clusters Catalyzing Epoxidation

Dai, Sheng,Ding, Bingjie,Gong, Xueqing,Hou, Zhenshan,Li, Difan,Tang, Xuan,Xu, Beibei,Yao, Yefeng,Zhang, Tong,Zheng, Anna,Zhou, Qingqing

, p. 8190 - 8203 (2021/07/26)

We present here that easily available organic salts can stabilize/modify niobium (Nb) oxo-clusters. The as-synthesized Nb oxo-clusters have been characterized by various methods. These Nb oxo-clusters were catalytically active for the epoxidation of allylic alcohols and olefins with H2O2 as an oxidant. Notably, Nb-OC@TBAF-0.5 appeared as highly dispersed nanosized particles and showed the highest catalytic activity, which can be attributed to the following reasons on the basis of characterization. First, the strong coordination of fluorine ions with Nb sites and the steric protection with bulky organic cations led to high stabilization and dispersion of the oxo-clusters in the course of the reaction. Second, a hydrogen-bond interaction between the coordinated fluorine atom and the -OH group of allylic alcohol favored the epoxidation reaction. Third, the electron density of Nb sites decreased due to the strong electron-withdrawing ability of F- adjacent to Nb sites, thus promoting the electrophilic oxygen transfer to the CC bond.

2,3-Dialkoxypropyl glyceryl ether and its preparation process as well as cosmetic composition containing same

-

, (2008/06/13)

Disclosed herein is a novel 2,3-dialkoxypropyl glyceryl ether and the preparation process for it. The above diglycerin dialkyl ether is readily prepared with high yield and purity by reacting its corresponding glycidyl ether with a protected glycerin to form a 1,3-dioxolan compound, followed by etherifying the thus formed 1,3-dioxolan compound into a dialkyl ether dioxolan compound, and then hydrolyzing the resultant dialkyl ether dioxolan compound. This diglycerin dialkyl ether is useful as an emulsifier, cleaner etc., and is preferably used as a component of cosmetic compositions. A cosmetic composition comprising the above 2,3-dialkoxypropyl glyceryl ether is also disclosed.
