2 3 5-Trichloropyridine（CAS# 16063-70-0) Nga korero
| whakataki | Ko te 2,3, 5-trichloropyridine he totoka kowhai marama me te takawaenga matū tino pai. Ka tauhohe te 2,3,5-trichloropyridine ki te waikawa whakarewa alkali ki te whakarite i te phenol 3,5-dichloro-2-pyridine, he mea tino nui mo te whakahiato o nga mite ngarara me te oxaloether otaota. Ka taea hoki te 2,3, 5-trichloropyridine te fluorinated ki te whakahiato i te 2, 3-difluoro-5-chloropyridine, ko te rauemi mata taketake mo te whakahiato o te herbicide alkynurate. |
| whakarite | 60 karamu o te mewaro i tapirihia ki te 1000mL ipu wha-waha, 100g Ko te 2,3,5,6-tetrachloropyridine me te 31.7g o te hydrazine hydrate i tapirihia, ka piki te pāmahana ki te 60-65 ℃, ka whakahaerehia te tauhohenga tiaki wera mo te 2 haora, ka mutu te tauhohenga, ka whakahekehia te pāmahana ki te 0-5 ℃, ka whakahekehia te pāmahana ki te 1 haora, ka tātarihia te totoka, ka 2,3 te totoka, I whakamarokehia te 5-trichlor6-hydrazinyl pyridine hydrate ki te whiwhi 101.6g o te totoka ma me te 96% te hua me te 98.5% te ihirangi. Tāpirihia te 100g 2,3,5-trichloro 6-hydrazinyl pyridine hydrate, 50g o te 5% konutai waiwai wairewa wai ki te 1000ml o wha-waha pounamu, whakaarahia te pāmahana ki te 70-75 ℃, tāpiri 387.6g o te 10% konutai hypochlorite wairewa wairewa dropwise, pupuri i te pāmahana ki te 70-75 ℃, tauhohe mo te 1 haora, mutu te tauhohenga, hauhautanga ki te 5-10 ℃, whakaohokia mo te 1 haora, tātari kia whiwhi 2,3, ka makuku te 5-trichloropyridine masivesivá i raro i te pehanga iti ki te whiwhi i te hua, he toka kowhai marama me te hua o te 95% me te ihirangi o 98%. |
