Sodium Propanoate

Convincing evidence that ester hydrolysis in base proceeds by the second of these two paths namely nucleophilic acyl substitution has been obtained from several sources In one experiment ethyl propanoate labeled with 0 m the ethoxy group was hydrolyzed On isolating the products all the 0 was found m the ethyl alcohol there was no 0 enrichment m the sodium propanoate... 

Any soluble salt of propanoic acid and a strong base would be suitable. Acceptable answers include sodium propanoate or potassium propanoate. 

Dehydrorotenone 1 can be readily transformed into rotenone 2 by reduction of the chromone to the chromanol followed by Oppenauer oxidation. Two elegant syntheses of dehydrorotenone 1 used DCC as a key reagent as follows (i) treatment of derrisic acid 3 with DCC/EtjN followed by reaction of the intermediate thus obtained with sodium propanoate in ethanol gave 1. (ii) Condensation of tubaic acid 4 with the pyrrolidine enamine derived from 5 in the presence of DCC also gave 1.

A buffer solution is prepared in such a way that the concentrations of propanoic acid and sodium propanoate are each 2.00 X 10- M. If the buffer equilibrium is described by... 

Calculate the pH of the buffer solution in Question 9.19 if the concentration of the sodium propanoate were doubled while the acid concentration remained the same. 

On isolating the products, all the O was found in the ethyl alcohol there was no O enrichment in the sodium propanoate. 

Sodium propanoate Sodium sulfobromophthalein Sodium tartrate Sodium tartrate dihydrate Sodium tetraphenylborate Sodium trifluoroacetate Solanid-5-ene-3,18-diol, (3(3)... 

Calcium and sodium propanoate are used commercially as preservatives in bread, cakes, and cheese to prevent the growth of bacteria and molds (see Figure 5.6). The parent acid, CH3CH2COOH, occurs naturally in Swiss cheese. The labels for these bakery products often contain the common name propionate, rather than the lUPAC-acceptable name propanoate. 

Salts of carboxylic acids are named in the same manner as are salts of inorganic acids Name the cation first and then the anion. Derive the name of the anion from the name of the carboxylic acid by dropping the suffix -ic acid and adding the suffix -ate. For example, the name of CH3CH2COO Na is sodium propanoate, and that of CH3(CH2)i4COO Na is sodium hexadecanoate (sodium palmitate).
