1-Naphthaleneacetic acid Usage And Synthesis
- Description1-naphthaleneacetic acid (NAA, also named as α-naphthaleneacetic acid) belongs to a class of organic compounds of naphthalenes, which contain a naphthalene moiety of two fused benzene rings. NAA is a synthetic auxin plant hormone. It is used as a plant growth regulator to control preharvest fruit drop, flower induction and fruit thinning in various crops such as apples, potatoes, olives, and citrus fruits. It is used as a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture and as herbicide. Applied as a dust or spray it delays dissolution of the abscission layer, retarding the fruit drop. The effect of NAA on plant growth is greatly dependent on the time of admission and concentration. When used after four weeks, NAA stimulates shoot growth, while full-time use limits growth. When used in a 4-week pulse, adventitious root growth is greatly increased.

- Purification MethodsCrystallise the acid from EtOH or water. [Beilstein 9 H 666, 9 IV 2424.]
- IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, chlorates nitrates, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).
- Waste DisposalIncineration. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
