Indalo:
1. Ukubonakala: I-METHYL 5,6-dichloronicotinate ilulwelo olungenambala.
2. I-Solubility: Inokunyibilika kwi-solvents ezininzi zezinto eziphilayo, ezifana ne-alcohol, i-ethers, i-hydrocarbons e-chlorinated, njl.
3. Indawo yokunyibilika kunye neqondo lokubila: Indawo yokunyibilika ye-METHYL 5,6-dichloronicotinate imalunga ne-68-71 degrees celcius, kwaye iqondo lokubila limalunga ne-175 degrees Celsius.
Sebenzisa:
I-1.METHYL 5,6-dichloronicotinate ingasetyenziselwa njengento ephakathi kwi-organic synthesis kwaye isetyenziswe kwi-synthesis yezinye izinto eziphilayo.
2. Isenokusetyenziswa nakwiindawo zokubulala izitshabalalisi, amayeza kunye nedayi.
Indlela:
Indlela yokudibanisa ye-METHYL 5,6-dichloronicotinate inokufezekiswa ngala manyathelo alandelayo:
1. Okokuqala, i-nicotinic acid (i-nicotinic acid) iphendula kunye ne-thionyl chloride (thionyl chloride) ukuvelisa i-nicotinic acid chloride (i-nicotinoyl chloride).
2. Emva koko, i-nicotinic acid chloride iphendulwa kunye ne-methanol ukuvelisa i-METHYL 5,6-dichloronicotinate.
Ulwazi ngoKhuseleko:
1. I-METHYL 5,6-dichloronicotinate yi-organic compound ecaphukisayo. Gwema ukudibanisa ngokuthe ngqo kwesikhumba kunye namehlo ngexesha lokusetyenziswa okanye ukudibanisa.
2. Ngethuba lokusebenza, kuyimfuneko ukuqinisekisa iimeko ezintle zomoya kwaye ugweme ukukhupha umphunga wayo.
3. Xa ugcina kwaye uphatha, kufuneka ugcinwe kude nomlilo kunye ne-oxidant.
4. Kwimeko yokuphefumula ngengozi okanye ukudibanisa, ngokukhawuleza uhlambe indawo echaphazelekayo ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
5. Xa usebenzisa i-METHYL 5,6-dichloronicotinate, Nceda uthobele ngokungqongqo iinkqubo zokusebenza ezifanelekileyo zokhuseleko kunye namanyathelo okukhusela umntu.
