Intshayelelo
I-2,6-Dichloronicotinic acid yi-organic compound. Oku kulandelayo kukwazisa ngokufutshane kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,6-dichloronicotinic acid:
Umgangatho:
- I-2,6-Dichloronicotinic acid yinto eqinileyo yekristale engenambala enyibilikayo kwizinyibilikisi zezinto eziphilayo ezifana neealkoholi kunye ne-ethers.
- Inevumba elinukayo kwaye idla ngokurhabula.
- Ibola kumaqondo obushushu aphezulu, ikhupha igesi yeklorini enetyhefu.
Sebenzisa:
- I-2,6-Dichloronicotinic acid ingasetyenziswa njengendawo ephakathi kwimveliso ye-pesticides kunye ne-herbicides.
- Ingasetyenziselwa ukuphendula kwe-chlorination kwi-organic synthesis, njengokulungiswa kwezinye iikhompawundi ze-organochlorine.
Indlela:
- I-2,6-Dichloronicotinic acid idla ngokulungiswa ngokuphendula i-nicotinic acid kunye ne-thionyl chloride okanye i-phosphorus trichloride.
Ulwazi ngoKhuseleko:
- I-2,6-Dichloronicotinic acid i-corrosion kwaye inokubangela ukutshisa kunye nokucaphuka ekudibaneni nolusu kunye namehlo. Uqhagamshelwano oluthe ngqo kufuneka luphetshwe.
- Xa usebenzisa okanye ugcina i-2,6-dichloronicotin, amanyathelo afanelekileyo okhuseleko afana nokunxiba iiglavu zokukhusela, izibuko, kunye nempahla yokukhusela kufuneka ilandelwe.
- Xa uphatha i-2,6-dichloronicotinic acid, indawo enomoya ococekileyo kufuneka iqinisekise ukuphepha ukuphefumula imiphunga okanye uthuli.
- I-2,6-dichloronicotinic acid inokuvelisa iimpendulo ezinobungozi xa ixutywe nezinye iikhemikhali, kwaye kufuneka kuthathelwe ingqalelo ukuphepha ukuxuba.
