反応プロフィール
A halogenated ester and amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

純化方法
This (±)-herbicide forms white crystals from Me2CO/EtOH and sublimes in vacuo. Large quantities can be distilled at high vacuum. Its solubilities at 20o in g/10mL are 0.09 (EtOH), 1.1 (Me2CO), 1.2 (xylene), 2.9 (*C6H6), and is nearly insoluble in H2O (0.3mg/L). The (±)-acid has [95977-28-9]. The R-ester enantiomer has m 76-77o (pale brown crystals from EtOH), [ ] D 20 + 3 5 . 9o (EtOH). It is the more active fatty acid synthase inhibitor (designated DPX-Y6202) used to control grassy weeds in broadleaf crops.
廃棄物の処理
It is the responsibility of chem-
ical waste generators to determine the toxicity and physical
properties and of a discarded chemical and to properly iden-
tify its classification and certification as a hazardous waste
and to determine the disposal method. United States
Environmental Protection Agency guidelines for the classifi-
cation determination are listed in 40 CFR Parts 261.3. In addi-
tion, waste generators must consult and follow all regional,
national, state, and local hazardous waste laws to ensure com-
plete and accurate classification and disposal methods.
