| Kev piav qhia |
o-Tolidine, tseem hu ua orthotolidine los yog 2-tolidine, yog cov tshuaj sib xyaw nrog cov mis molecular (C6H4(CH3)NH2)2. Nws yog ib tug dawb mus rau reddish-xim, combustible, aromatic amine uas emits tshuaj lom fumes ntawm nitrogen oxides thaum rhuab mus decomposition. Ob peb isomers paub; cov 3-tolidine derivative kuj tseem ceeb rau kev lag luam. Nws yog cov xim tsis muaj xim txawm tias cov qauv coj mus muag feem ntau muaj xim. Nws yog me ntsis soluble hauv dej. Nws tsim cov ntsev nrog cov kua qaub, xws li hydrochloride, uas yog muag. 2-Tolidine tuaj yeem tsim los ntawm kev hloov kho benzidine los ntawm hydrazine derivative tau los ntawm 2-nitrotoluene. |
| Chemical Properties |
o-Tolidine yog dawb mus rau reddish siv lead ua los yog hmoov thiab muaj ib tug zoo li aniline tsw. Nws yog soluble hauv cawv, ether, thiab dilute acid, tab sis tsuas yog me ntsis soluble hauv dej. Nws muaj qhov nyiam ua kom tsaus ntuj thaum raug huab cua thiab feem ntau siv rau hauv daim ntawv muab tshuaj txhuam los yog ntub cov ncuav mog qab zib. Qhov kev sib xyaw no ua haujlwm tseem ceeb hauv kev tsim cov dyes ntau. |
| Siv |
o-Tolidine yog siv dav hauv kev tsim cov dyes, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov azo soluble dyes thiab insoluble pigments rau textile, tawv, thiab ntawv sectors. Tsis tas li ntawd, Nws kuj yog siv los ua ib qho rhiab colorimetric reagent rau kev tsom xam ntawm kub thiab dawb chlorine hauv dej. |
| Siv |
3,3'-Dimethylbenzidine siv rau kev npaj cov khoom siv polyimide thiab epoxy resin. |
| Kev npaj |
Muaj ob txoj hauv kev siv los ua o-Tolidine. Thawj txoj kev suav nrog kev txo qis ortho-nitrotoluene rau 1, 2-diorthotolylhydrazine, uas tom qab ntawd rov kho cov kua qaub. Qhov thib ob txoj kev yuav txo tau o-nitrotoluene siv zinc plua plav thiab caustic soda, ces converting lub resulting hydrazotoluene rau o-Tolidine los ntawm boiling nws nrog hydrochloric acid. Thaum ib qho ntawm cov txheej txheem no tiav lawm, o-Tolidine tuaj yeem raug muab rho tawm thiab ua kom huv los ntawm cov txheej txheem xws li hnyav extraction thiab recrystallization. |

| Reactivity Profile |
CI 37230 yog rhiab heev rau raug lub teeb. Tej zaum yuav rhiab heev rau lub sij hawm raug rau huab cua. Lub hauv paus tsis muaj zog uas tsim cov ntsev nrog hydrochloric acid lossis sulfuric acid. CI 37230 tuaj yeem ua acetylated. Incompatible nrog cov neeg ua haujlwm muaj zog. |
| Hazard |
Qhov muag, zais zis thiab lub raum irritant, zais zis mob cancer, thiab methemoglobinemia. Ua tau carcinogen. |
| Health Hazard |
Cov ntaub ntawv ntawm toxicity thiab carcinogenicity ntawm o-tolidine yog tsawg heev. o-Tolidine feem ntau muaj lwm yam kab mob biphenylamine. Nws cov qauv thiab tshuaj lom neeg zoo ib yam li cov benzidine. Yog li ntawd, cov tshuaj toxicity yuav tsum zoo ib yam li cov benzidine. o-Tolidine yog nqus mus rau hauv lub cev los ntawm daim tawv nqaij, ua pa, thiab gastrointestinaltract. Qhov mob qhov ncauj thiab dermal toxicity yog nruab nrab hauv cov tsiaj sim. Tus nqi ntawm qhov ncaujLD50 hauv nas yog nyob rau hauv thaj tsam ntawm 400 mg / kg. o-Tolidine tsim cov qog nqaij hlav zais zis hauv cov tshuaj ntsuam xyuas. Tsis tas li ntawd, cov qog nqaij hlav hauv lwm cov ntaub so ntswg tau sau tseg hauv qee cov tsiaj. ACGIH teev cov khoom no raws li kev xav tias tib neeg carcinogen. |

| Ntxim yuav nphav raug |
Tshaj li 75% ntawm o-tolidine yog siv los ua cov xim thiab ua ib qho nruab nrab hauv kev tsim cov khoom siv roj hmab, dyestuffs, pigments thiab tshuaj tua kab. Kwv yees li ntawm 20% ntawm o-tolidine yog siv los tsim cov polyurethane-based high-strength elastomers, coatings, thiab tawv yas. o-Tolidine kuj tau siv me me hauv cov khoom siv tshuaj chlorine los ntawm cov tuam txhab dej thiab cov tswv pas dej da dej. Siv los ua ib tus neeg saib xyuas kuaj ntshav los kuaj ntshav. |
