Daim Ntawv: p-toluidine yog ib qho tsis muaj xim, ci ntsa iab flaky crystal, lossis dawb mus rau daj daj, thiab kuj tseem yuav tshwm sim hauv daim ntawv tan mus rau xim av.
Kev yaj: Me ntsis yaj hauv dej, tab sis yaj tau ntau yam kuab tshuaj xws li ethanol, ether, benzene, thiab hydrochloric acid.
Lwm yam khoom siv lub cev: Melting point: Feem ntau ntawm 41-46°C 23. Boiling point: 200°C (siab ib txwm). Qhov ceev: Qhov ceev sib piv yog li 0.9619 txog 0.973 g/mL (ntawm 25°C). Refractive index: Kwv yees li 1.5534 txog 1.5636 34. Flash point: Kwv yees li 86°C lossis 192°F. p-Toluidine feem ntau yog siv ua xim nruab nrab thiab nruab nrab ntawm cov tshuaj pyrimethamine hauv kev lag luam, tab sis nws yuav tsum tau sau tseg tias nws yog tshuaj lom thiab yog ib qho methemoglobin muaj zog, yog li nws yuav tsum tau siv nrog kev ceev faj.
Hauv kev xaus, p-toluidine muaj ntau hom, thiab nws cov khoom siv lub cev sib txawv nyob ntawm daim ntawv thiab cov xwm txheej.
Kev siv p-toluidine
Cov tshuaj reagent analytical: p-toluidine yog siv los ua cov tshuaj reagent hauv kev tshuaj chemistry los pab ua cov tshuaj tshwj xeeb. Kev tsim cov xim zas: Nws yog ib qho nruab nrab rau ntau cov xim zas, xws li cov xim liab GL, methylamine liab pas dej, fuchsin yooj yim, thiab siv dav hauv kev tsim cov xim zas hauv cov ntaub, luam ntawv thiab lwm yam lag luam. Tshuaj nruab nrab: Hauv kev lag luam tshuaj, p-toluidine yog ib qho nruab nrab rau cov tshuaj pyrimethamine, uas yog qhov tseem ceeb rau kev tsim cov tshuaj. Lwm cov ntawv thov: p-toluidine kuj tseem siv tau los npaj 1-hydroxy-4-(p-toluidine)-anthraquinone, uas yog siv los ua cov tshuaj reagent rhiab heev rau kev txiav txim siab ntawm boron thiab feem ntau yog siv rau cov xim ntawm polyester fiber pulp.
p-Toluidine, tseem hu ua 4-toluidine, yog ib qho organic compound nrog cov mis tshuaj C7H9N. Nws yog ib qho tsis muaj xim, ci ntsa iab, me ntsis soluble hauv dej, tab sis soluble hauv ethanol, ether, benzene, thiab hydrochloric acid. Nws yuav tsum nco ntsoov tias p-Toluidine yog lom, ib qho methemoglobin muaj zog, thiab tuaj yeem ua rau lub zais zis thiab urethra khaus thiab ua rau hematuria, yog li nws yuav tsum siv nrog kev ceev faj.
