4-Bromobenzaldehyde diethyl acetal is an acetal derivative of 4-bromobenzaldehyde. Its enthalpy of vaporization at boiling point (527.15K) is 46.499kjoule/mol. 4-Bromobenzaldehyde diethyl acetal can be synthesized by reacting 4-bromobenzaldehyde with methanol in the presence of triethylamine and titanium chloride.

Check Digit Verification of cas no

The CAS Registry Mumber 24856-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,5 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24856-58:
(7*2)+(6*4)+(5*8)+(4*5)+(3*6)+(2*5)+(1*8)=134
134 % 10 = 4
So 24856-58-4 is a valid CAS Registry Number.

Preparation of a Yb(III)-Incorporated porous polymer by post-Coordination: Enhancement of gas adsorption and catalytic activity

Kim, Hyungwoo,Cha, Min Chul,Park, Hyun Woo,Chang, Ji Young

, p. 5291 - 5297 (2013)

We synthesized a Yb(III)-incorporated microporous polymer (Yb-ADA) and studied its gas adsorption property and catalytic activity. The adamantane-based porous polymer (ADA) was obtained from an ethynyl-functionalized adamantane derivative and 2,5-dibromoterephthalic acid through Sonogashira-Hagihara cross-coupling. ADA had two carboxyl groups which were used for Yb(III) coordination under basic conditions. The Brunauer-Emmett-Teller (BET) surface area of ADA was 970 m2 g-1. As Yb(III) ions were incorporated into ADA, the surface area of the polymer (Yb-ADA) was reduced to 885 m2 g-1. However, Yb-ADA exhibited a significantly enhanced CO2 adsorption capacity despite the reduction of surface area. The CO2 uptakes of ADA and Yb-ADA were 1.56 and 2.36 mmol g-1 at 298 K, respectively. The H2 uptake of ADA also increased after coordination with Yb(III) from 1.15 to 1.40 wt % at 77 K. Yb-ADA showed high catalytic activity in the acetalization of 4-bromobenzaldehyde and furfural with trimethyl orthoformate and could be reused after recovery without severe loss of activity.

α-Chymotrypsin-Induced Acetalization of Aldehydes and Ketones with Alcohols

Jiang, Guofang,Lan, Jin,Le, Zhanggao,Xie, Zongbo,Yang, Jiangnan,Zhu, Haibo

, p. 2121 - 2126 (2020/07/14)

This is the first report of a simple and general method for acetalization of aldehydes via an α-chymotrypsin-induced reaction under mild conditions. A broad range of aromatic and heteroaromatic aldehydes have been acetalized under neutral conditions in good yields using a catalytic amount of chymotrypsin.

Synthesis, structural determination and catalytic study of a new 2-D chloro-substituted zinc phosphate, (C8N2H20)[ZnCl(PO3(OH))]2

Rayes, Ali,Herrera, Raquel P,Moncer, Manel,Ara, Irene,Calestani, Gianluca,Ayed, Brahim,Mezzadri, Francesco

, (2019/11/03)

A novel chloro-substituted zinc-phosphate, (C8N2H20)[ZnCl(PO3(OH))], has been synthesized by a slow evaporation method in the presence of 1,3-cyclohexanebis- (methylamine), which acts as a template. The structure consists of vertex linked ZnO3Cl and PO3(OH) tetrahedral, assembled into corrugated porous layers [ZnCl(PO3(OH))2]∞ with (4.82) topology. The optical properties were also investigated using Diffuse Reflecting Spectroscopy (DRS), showing that the title compound has semiconducting properties. In addition, the catalytic activity of (C8N2H20)[ZnCl(PO3(OH))]2 has been tested in the acetalisation reaction of aldehydes. The title compound displayed a high catalytic activity with practically total conversion in many examples using MeOD as solvent and as the sole source of acetalisation. More importantly, the reaction crudes are very clean and only the preferred products are found in the NMR spectra.
