Nhanganyaya
(1H) -one (1H)-one) isanganiswa ine organic formula C6H7NO2. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
(1H) -imwe ikristaro chena yakasimba, isinganhuhwi. Inogadzikana pakudziya kwakajairika, asi inogona kuora pakupisa kwakanyanya. Kunyungudika kwayo kuri pakati pe140-144 madhigirii Celsius.
Shandisa:
(1H) -imwe ine dzakasiyana siyana dzekushandisa mune organic synthesis. Inogona kushandiswa seyepakati mune organic synthesis yekubatanidza mamwe makomisheni, akadai semishonga, dhayi uye mishonga yezvipembenene. Mukuwedzera, inogona zvakare kushandiswa sesimbi inogadzirisa reagent ye catalytic reactions.
Kugadzirira nzira:
Pane nzira mbiri huru dzekugadzirira (1H) -imwe. Imwe ndeyekuunzwa kweboka rehydroxyl neboka remethyl mumhete yepyridine nealkylation yeboka rehydroxyl repicoline. Imwe nzira ndeyekuita hydroxyl alkylation reaction papyridine mhete kuunza boka rehydroxyl neboka remethyl. Iyo chaiyo nzira yekugadzirira inogona kusarudzwa maererano nezvinodiwa chaizvo uye mamiriro.
Zvekuchengetedza
(1H) -imwe haina muchetura zvishoma asi inofanira kubatwa nekuchenjerera. Panguva yekushanda, kutarisirwa kunofanira kutorwa kuti urege kutarisana zvakananga neganda nemaziso, uye kuve nechokwadi kuti kushanda kuri munzvimbo ine mhepo yakanaka. Kana netsaona kuonana, anofanira pakarepo sukurudza nemvura uye nenguva kurapwa. Mukuwedzera, inofanira kuchengetwa mumudziyo wakavharwa, kure nemoto uye oxidizing agents.
Ndokumbira utarise kuti paunenge uchishandisa nekubata chero chemakemikari, iwe unofanirwa kutevedzera kwakaringana marabhoritari maitiro, uye tarisa kune yekuchengetedza data sheet (SDS) yechinhu uye kutungamira kwemasangano ehunyanzvi.
