41122-70-7 Usage
Chemical Properties
White Crysstalline
Uses
Used in thermoresponsive meso/nanostructured PS-b-PEO block copolymer-dispersed liquid crystal.4′-hexyl-4-biphenylcarbonitrile, 4′-octyloxy-4-biphenylcarbonitrile and their composite liquid crystals were studied for dielectric properties.Proposed applications are in the field of thermo- and electro optical devices (e.g. optical shutters, smart windows, optical sensors,memories and flexible display devices), n phase array optics (e.g. as switchable birefringent phase shifters).
General Description
Milky-white thick liquid.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Nitriles, such as 4'-HEXYL-4-BIPHENYLCARBONITRILE, may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.
Fire Hazard
4'-HEXYL-4-BIPHENYLCARBONITRILE is probably combustible.
Check Digit Verification of cas no
The CAS Registry Mumber 41122-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,2 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41122-70:
(7*4)+(6*1)+(5*1)+(4*2)+(3*2)+(2*7)+(1*0)=67
67 % 10 = 7
So 41122-70-7 is a valid CAS Registry Number.

New methods of synthesis of mesomorphic 4-n-alkyl- and 4-n-alkoxy-4'-cyanobiphenyls are developed, based on the palladium catalyzed highly selective reactions of 1,4-dibromobenzene with alkyl and aryl Grignard reagents.
NEW SIMPLE METHOD FOR OBTAINING 4-n-ALKYL-4 prime -CYANOBIPHENYLS.

, p. 251 - 259 (2007/10/02)
A new method is described of obtaining 4-n-alkyl-4 prime -cyanobiphenyls from biphenyl. First biphenyl is acrylated and the resulting ketone is reduced in conditions of the Huang-Minlon reaction; next the obtained 4-n-alkylbiphenyl is converted to 4-n-alkyl-4 prime -iodobiphenyl which readily reacts with copper cyanide giving the required nitrile with a good yield.
