ABIETIC ACID Usage And Synthesis

Chemical Properties	yellow resinous powder, crystals or chunks
Uses	Abietic Acid is the primary component of resin acid found commonly in rosin. Abietic Acid exhibited potent testosterone 5α-reductase inhibitory activity in vitro.
Definition	ChEBI: An abietane diterpenoid that is abieta-7,13-diene substituted by a carboxy group at position 18.
General Description	Yellowish resinous powder.
Reactivity Profile	ABIETIC ACID reacts exothermically with bases, both organic (for example, the amines) and inorganic. Can react with active metals to form gaseous hydrogen and a metal salt. Such reactions are slow if the solid acid remains dry. Can react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slow for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.
Health Hazard	ACUTE/CHRONIC HAZARDS: Slight fire hazard, slight explosive hazard as dust. Low toxicity.
Fire Hazard	Combustible.
Contact allergens	Abietic acid is probably the major allergen of colophony, along with dehydroabietic acid, by way of oxidation products. Its detection in a material indicates that allergenic components of colophony are present
Purification Methods	Filter, dry it in a vacuum (over KOH or CaSO4) and store it in an O2-free atmosphere. It can also be purified via the anhydride, tritylabietate and the potassium, piperidine and brucine salts. max : nm(log ): 2343(4.3), 241(4.4), 2505(4.2), 235(4.34) and 240(4.36) in Et.
