4-Nitrophenetole(CAS#100-29-8)
quality
Pale yellow makristasi. Panonyungudika i60 °C (58 °C), panofashaira i283 °C, 112~115 °C (0.4kPa), uye density inosvika 1. 1176. Inonyungudika zvishoma mumvura, ethanol inotonhora uye petroleum inotonhora. ether. Soluble muether, soluble in inopisa ethanol uye inopisa petroleum ether.
Nzira
Inogadzirwa ne etherification reaction ye p-nitrochlorobenzene uye ethanol. P-nitrochlorobenzene uye ethanol yakawedzerwa kune kettle yekuita, tembiricha yakasimudzwa kusvika 82 ° C, uye ethanol sodium hydroxide solution yakawedzerwa kudonha, uye maitiro akaitwa pa85 ~ 88 ° C kwe3h. Iyo alkalinity yemhinduro mhinduro yakaderedzwa kusvika pazasi 0.9%, yakanyoroveswa kusvika 75 ° C, uye iyo pH kukosha kwakagadziridzwa kusvika 6.7 ~ 7 ine concentrated hydrochloric acid. Mushure mokumira uye stratification, mafuta emafuta anotorwa uye sodium nitrophenol inoshambidzwa nekupisa mvura, uye mafuta emafuta anonyungudutswa pasi pekuderedza kuderedzwa, uye chikamu che214 ~ 218 ° C (2. 66 ~ 5.32kPa) chinotorwa. sechigadzirwa ichi.
use
inoshandiswa sepakati pemishonga nedhayi. Inoshandiswa mukurapa kugadzira phenacetin, nezvimwe.
kuchengeteka
Ichi chigadzirwa chine chepfu. Zvese inhalation uye kupinza zvinokuvadza kune hutano. Pfekai magirazi ekuchengetedza, pfekai mahovhorosi ekupinda muchetura, uye pfekai-yega-priming sefa yemasks eguruva kana masangana neguruva.
Iyo yekurongedza inogadzirwa nediki madhiramu esimbi akavhurika, screw-muromo mabhodhoro egirazi, iron lid press-muromo mabhodhoro egirazi, mabhodhoro epurasitiki kana mbiru dzesimbi (magaba) kunze kwemapuranga emapuranga. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo. Chengetedza kure nemoto, kunobva kupisa, chengetedza kubva kuzuva rakananga, uye simbisa mudziyo. Chiedza kurodha nekuburitsa kana uchibata.
