6-Methylpyridine-2 4-diol (CAS# 3749-51-7)
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |
| Ikhodi ye-HS | 29333990 |
| Inothi Lengozi | Iyacasula |
Isingeniso
I-(1H)-one (1H)-one) iyinhlanganisela ye-organic ene-chemical formula C6H7NO2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
(1H) -enye iyikristalu emhlophe eqinile, engenaphunga. Iyazinzile emazingeni okushisa ajwayelekile, kodwa ingase ibole emazingeni okushisa aphezulu. Iphuzu layo lokuncibilika liphakathi kuka-140-144 degrees Celsius.
Sebenzisa:
(1H) -enye inezinhlobonhlobo zezinhlelo zokusebenza ku-organic synthesis. Ingasetshenziswa njengendawo ephakathi ku-organic synthesis yokuhlanganiswa kwezinye izinhlanganisela, njengemithi, odayi kanye nezibulala-zinambuzane. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-reagent yensimbi eyinkimbinkimbi yokusabela kwe-catalytic.
Indlela Yokulungiselela:
Kunezindlela ezimbili eziyinhloko zokulungiselela (1H) -enye. Okunye ukwethulwa kweqembu le-hydroxyl neqembu le-methyl eringini ye-pyridine nge-alkylation yeqembu le-hydroxyl le-picoline. Enye indlela ukwenza ukusabela kwe-hydroxyl alkylation eringini ye-pyridine ukwethula iqembu le-hydroxyl neqembu le-methyl. Indlela ethile yokulungiselela ingakhethwa ngokwezidingo nezimo ezithile.
Ulwazi Lokuphepha:
(1H) -enye inobuthi obuncane kodwa kufanele iphathwe ngokuqapha. Ngesikhathi sokusebenza, ukunakekelwa kufanele kuthathwe ukugwema ukuthintana ngqo nesikhumba namehlo, nokuqinisekisa ukuthi ukuhlinzwa kusendaweni enomoya omuhle. Uma ukuthintana ngephutha, kufanele ngokushesha hashaza ngamanzi kanye nokwelashwa okufika ngesikhathi. Ngaphezu kwalokho, kufanele igcinwe esitsheni esivaliwe, kude nomlilo kanye nama-oxidizing agents.
Sicela uqaphele ukuthi lapho usebenzisa futhi uphatha noma iyiphi into yamakhemikhali, kufanele ulandele izinqubo ezifanele zaselabhorethri, futhi ubhekisele kudatha yezokuphepha (SDS) yale nto kanye neziqondiso zezikhungo zochwepheshe.
