Cinnamic acid is an organic compound with the formula C6H5CHCHCO2H. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. It exists as both a cis and a trans isomer, although the latter is more common.
Because of the low-cost and large-scale availability of formic acid by carbonylation of methanol and hydrolysis of the resulting methyl formate, sodium formate is usually prepared by neutralizing formic acid with sodium hydroxide. Sodium formate is also unavoidably formed as a by-product in the final step of the pentaerythritol synthesis and in the crossed Cannizzaro reaction of formaldehyde with the aldol reaction product trimethylol acetaldehyde [3-hydroxy-2,2-bis(hydroxymethyl)propanal].
Sodium ethoxide (also is the organic compound with the formula C2H5ONa) is a white to yellowish powder that dissolves in polar solvents such as ethanol. It is commonly used as a strong base. Few procedures have been reported to the anhydrous solid. Instead the material is typically prepared in a solution with ethanol. It is commercially available and as a solution in ethanol. It is easily prepared in the laboratory by treating sodium metal with absolute ethanol.
Benzimidazole was used as template compound in the preparation of molecularly imprinted polymer via electropolymerization and electrodeposition of pyrrole on a pencil graphite electrode . It was also used in the preparation of benzimidazolium surfactant, 1-hexadecyl-1H-benzimidazole.
