Peb qhia peb txoj kev siv hluavtaws ntawm Fluroxypyr. Thaum cov txheej txheem no siv tau, txhua txoj hauv kev yuav sib txawv vim qhov sib txawv ntawm qhov muaj, tus nqi, thiab kev pheej yig ntawm cov khoom pib. Yog tias qhov kev siv tau zoo ntawm cov txheej txheem no tuaj yeem ua tib zoo tuav, Fluroxypyr tuaj yeem npaj dav ua lag luam kom tau raws li qhov xav tau ntawm kev ua lag luam.
Fluroxypyr yog ib qho tshuaj tua kab uas siv dav hauv cov chav kawm ntawm cov tshuaj tua kab uas muaj ntxhiab. Nws cov qauv tshuaj yog 2-[(4-amino-3, 5-dichloro-6-fluoro-2-pyridinyl)oxy] acetic acid, thiab nws cov tshuaj Cov mis mos yog C9H6Cl2FN2O3. Cov kev tshawb fawb tau pom tias Fluroxypyr muaj ntau yam tshuaj reactivity.
Ua ntej, Fluroxypyr tuaj yeem ua rau cov tshuaj tiv thaiv acid-puag. Nws yog cov kua qaub tsis muaj zog uas ua rau lub hauv paus muaj zog xws li sodium hydroxide los tsim cov ntsev sib xws. Piv txwv li, thaum Fluroxypyr yaj nyob rau hauv dej, thiab txaus NaOH ntxiv, tus nqi pH ntawm cov tshuaj yuav nce, cov sodium ntsev yog generated, thiab dej molecules raug tso tawm.
Qhov thib ob, Fluroxypyr tuaj yeem hnov mob nrog qee cov tshuaj oxidizing, xws li hydrogen peroxide, ozone, thiab lwm yam. Cov tshuaj tiv thaiv no ua rau cov qauv molecular ntawm Fluroxypyr, ua rau nws tsis ua haujlwm. Yog li ntawd, thaum lub sij hawm huv si, cov oxidizing agents feem ntau yog siv los tshem tawm Fluroxypyr uas yuav nyob twj ywm hauv cov dej khib nyiab.
Tsis tas li ntawd, Fluroxypyr tuaj yeem txo qis, piv txwv li, mus rau qhov sib thooj carboxylic acid. Cov tshuaj tiv thaiv no feem ntau yog ua los ntawm qhov kub thiab txias, siab siab thiab nyob rau hauv lub xub ntiag ntawm ib tug txo tus neeg sawv cev. Cov khoom txo qis yog suav tias muaj kev nyab xeeb dua li Fluroxypyr, uas yuav ua rau muaj kev phiv hauv cov hom tsis yog hom phiaj, tshwj xeeb tshaj yog cov tsiaj.
Fluroxypyr tuaj yeem hloov pauv cov tshuaj tiv thaiv nrog lwm cov tshuaj. Piv txwv li, reacting nrog ammonium sulfate tuaj yeem tsim cyclohexyl - -carbamate hydrochloride; reacting nrog hydrogen cyanide tuaj yeem tsim cyclohexanoyl cyanide; reacting nrog ammonia tuaj yeem tsim cyclohexyl- -carbamate, thiab lwm yam.
Nyob rau hauv xaus, raws li ib tug dav siv tshuaj tua kab mob, Fluroxypyr muaj ntau yam tshuaj reactivity zog. Cov tshuaj tiv thaiv no tseem ceeb heev rau kev nkag siab txog txoj hauv kev metabolic, tus cwj pwm degradation, thiab cov tshuaj lom ntawm Fluroxpyr.
