GENERAL DESCRIPTION AND APPLICATIONS |
||
| Crotonic acid is a member of short and unsaturated chain carboxylic acids; trans-2-butenoic acid in IUPAC sysytem name and 3-methylacrylic acid in acrylic acid series naming. It is a white to off-white crystals; soluble in water (the solution is a weak acid); melting at 71 C; boiling at 185 C. It reacts violently with bases, oxidants, reducing agents. It is found in croton oil used as a standard irritant in pharmacological research; laxative and poisonous to human. Tiglic acid is structurally the trans- form of methyl branched crotonic acid found in croton oil (trans-2,3-Dimethylacrylic acid in acrylic acid series naming). The cis- form of methyl branched crotonic acid is called angelic acid obtainable naturally from roots of Angelica plant. They are onoclinic poisonous crystals; soluble in hot water. They have a reactive double bond and carboxylic group in one molecule. They can be used as co-monomers for polymerization to prepare functional polymers as well as in protein sequencing and enzyme inhibiting. Their derivatives, acyl halides, anhydrides, esters, amides and nitriles, are used in making target products such as flavoring agents, internal plasticizers, pesticides, dyes, textile treatment agents, fungicides, and pharmaceuticals through further reactions of substitution, catalytic reduction, metal hydride reduction, diborane reduction, keto formation with organometallic reagents, electrophile bonding at oxygen, and Claisen condensation on carboxylic group and electrophilic additions, reduction, oxidation, radical additions, substitution and dienes formation on double bond. Crotonoyl chloride is used in agrochemicals and pharmaceuticals manufacturing. It is also used as an intermediate for dyes, textile auxiliaries, peroxide compounds. | ||
