cinnamic's Usage Examples:

The residual liquor is filtered and acidified with hydrochloric acid, when cinnamic acid is precipitated, C 6 H 5 CH0+CH 3 000Na= C 6 H 5 CH :CH 000Na-}-H 2 O.

CINNAMIC ACID, or Phenylacrylic Acid, C9H80 2 or C 6 H 5 CH: CH COOH, an acid found in the form of its benzyl ester in Peru and Tolu balsams, in storax and in some gumbenzoins.

It does not appear to contain cinnamic acid.

It contains about 20% of cinnamic acid in addition to 18 or even more of benzoic. (3) Palembang benzoin, an inferior variety, said to be obtained from Styrax benzoin in Sumatra, consists of greyish translucent resinous masses, containing small white opaque tears.

It may be obtained from storax by distillation with water, and synthetically by heating cinnamic acid with lime, by the action of aluminium chloride on a mixture of vinyl bromide and benzene, by removing the elements of hydrobromic acid from bromethylbenzene by means of alcoholic potash, or, best, by treating (-bromhydrocinnamic acid with soda, when it yields styrolene, carbon dioxide and hydrobromic acid.

Cinnamic aldehyde ((3-phenyl acrolein), C6H5�CH: CH�CHO, an unsaturated aromatic aldehyde, is the chief constituent of cinnamon oil.

Chromic acid oxidizes it to benzoic acid; zinc and acetic acid reduce it to cinnamic acid, C 6 H 5 CH:CH CO 2 H, whilst sodium amalgam reduces it to hydrocinnamic acid, C6H5 CH2 C02H.

Phenylpropiolic acid, C 6 H 5 C:C CO 2 H, formed by the action of alcoholic potash on cinnamic acid dibromide, C 6 H 5 CHBr CHBr CO 2 H, crystallizes in long needles or prisms which melt at 136-137° C. When heated with water to 120° C. it yields phenyl acetylene CsH b C; CH.
