The carboxylic acids used were propionic, butyric, valeric
and benzoic acids.
The synthesis of new polymer VALPOx with active carboxylic acid moiety was achieved via conventional aromatic nucleophilic substitution polymerization technique from 4,4,-bis(4-hydroxyphenyl) valeric
acid and 2,5-bis(4-fluorophenyl)-1,3,4-oxadiazole; the polycondensation was carried out at elevated temperature in NMP/toluene azeotrope in presence of anhydrous pulverised potassium carbonate as catalyst.
Poly(N-vinyl-2-pyrrolidone-co-acrylic acid) copolymers were synthesized by free radical copolymerization of monomers in 75:25 (v solvent : v reactants ) tetrahydrofuran (THF) using 4,4'-azobis(4cyano valeric
acid) (ACVA) as the initiator.
Scomplexes of Cu(II) and Ni(II) with acetone and acetylaldehyde hydrazones derivered from valeric

Even its smell can have a calming effect on the brain - chocolate also contains theobromine and valeric

15 CHOCOLATE contains stress-relieving properties as it contains valeric
acid - which is a known relaxant and tranquilliser.
But as far as horrific smells go, valeric
acid takes the cake.
And if that's not enough to chill you out, your favourite treat also contains valeric
acid, which is a known relaxant and tranquilliser.
Other researchers have successfully used salient aversive stimuli, such as pictures, to induce nausea directly (Mandel, 1970) or have administered nauseating substances such as ammonium sulphide (Colson, 1972) and valeric
acid (Maletzky, 1973).

Sudol of the Newark Star-Ledger, reviewing Roxas in the Joyce Trisler company - with whom she danced after leaving the Philippines in 1979 and before joining Ailey in 1984 - said she "set herself aside from the group with dancing more passionate and self-revelatory than any of the others permitted themselves.
