Uses

5-Chloro-2-pentanone used in the preparation of destructible surfactants.

Check Digit Verification of cas no

The CAS Registry Mumber 5891-21-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5891-21:
(6*5)+(5*8)+(4*9)+(3*1)+(2*2)+(1*1)=114
114 % 10 = 4
So 5891-21-4 is a valid CAS Registry Number.

A novel composite electrode material derived from bisferrocenyl-functionalized GO and PANI for high performance supercapacitor

Ahadzadeh, Iraj,Mohammadi, Reza,Payami, Elmira,Teimuri-Mofrad, Reza

, (2020)

A novel bisferrocenyl based epoxy compound was synthesized to be used for further surface modification of graphene oxide (GO). GO surface was firstly modified with ethylenediamine (EDA) as an amine linker and then bisferrocenyl based epoxy compound was covalently grafted to the GO surface through the epoxide ring opening reaction. Afterwards, polyaniline (PANI) nanofibers were physically adsorbed onto the surface of the modified GO to obtain a potentially high-performance nanocomposite for battery-type supercapacitor applications. The surface modification, crystalline structure, morphology, composition, and microstructure of the synthesized nanocomposites were further investigated using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) and N2 adsorption/desorption analyses, respectively. Also, the electrochemical behavior of the synthesized nanocomposites was investigated by electrochemical methods of cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), galvanostatic charge-discharge measurement (GCD). The final nanocomposite electrode exhibited a charge storage capacity of 272 mAh g?1, and capacity retention of 89 % over 3000 CV cycles. A high energy density of 69.3 Wh kg?1 and high power density of 6171 W kg?1 were achieved in a symmetrical two-electrode configuration.

Paragraph 0061; 0072; 0078-0079, (2020/07/21)

The invention relates to a synthesis method of intermediate farnesyl acetone and a method for synthesizing vitamin E, vitamin K1, vitamin K2 side chain isovegetable alcohol, plant alcohol and geranyl geraniol by using farnesyl acetone, and concretely relates to hydrogenation of 5 - farnesyl -2 - acetone and farnesyl acetone through three Grignard reaction to obtain plant ketone. The farnesyl acetone reacts with the vinyl chloride Grignard reagent to obtain geranyl linalool, the aromatic leaf-based geraniol is rearranged under acid catalysis, or farnesyl acetone is directly reacted with the hydroxyl-protected 2 - chloroethanol Grignard reagent to obtain geraniol. The plant alcohol is reacted with the vinyl chloride Grignard reagent to obtain the plant alcohol, and the plant alcohol is directly reacted with the hydroxyl-protected 2 - chloroethanol Grignard reagent to obtain the plant alcohol. The method has the advantages of cheap and easily available starting materials, short synthetic process steps, low product cost and the like. (by machine translation)
