Picric acid: cos piav qhia tshuaj

Picric Acid - yog ib tug tham tshuaj tshuaj uas yog ib tug nitro derivative ntawm phenol. Los ntawm txoj kev, qhov no compound yog paub nyob rau hauv science raws li "TRINITROPHENOL". Substance nws tus kheej thiab nws cov ntsev yog siv raws li explosives.

Picric acid: mis thiab lub zog

Trinitrophenol mis yog raws li nram no:

C6H2 (NO2) 3OH

Nyob rau hauv cov ntshiab daim ntawv no, picric acid yog ib tug khoom, uas muaj phaj zoo li muaju. Tej muaju tej zaum yuav yog tsis muaj kob los yog muaj ib tug me ntsis yellowish tint. Lub melting point ntawm no cov ntaub ntawv uas yog + 122.5 degrees Celsius.

Trinitrophenol saj heev iab, thiab nws cov hmoov av irritates lub qhov ntswg nqe vaj lug kub. Ntev nqus tau pa tshuaj teeb meem rau cov tib neeg kab, txij li thaum nws ua rau yus lom, lub raum puas tsuaj thiab cov tsos ntawm daim tawv nqaij kab mob. Tshuaj thiab undesirable kev sib cuag nrog lub qog ua kua week. Piv txwv li, conjunctiva qhov muag tom qab tsoo nws picric acid hmoov av yuav daj.

Picric acid: tshuaj nyob tus yeees thiab lub ntsiab yam ntxwv

TRINITROPHENOL tsis zoo soluble nyob rau hauv dej, txawm hais tias tus kub tsub kom lub solubility tsis nce. Txawm li cas los, qhov zoo tagnrho kuab rau lub substance yog benzene thiab methanol, chloroform thiab acetone.

Picric acid yog tseem muaj peev xwm sawv ntawm txoj kev ua li ntawd-hu ua eutectic mixtures. Qhov tseeb hais tias lub siab melting point ua ib co kev teeb meem nrog cov khoom ntawm cov mos txwv. Thiab thaum tsim sib tov trinitrokrezolom nitronaphthalene los yog daim duab tej zaum yuav yog cov txo.

Nws yuav tsum tau muab sau tseg tias TRINITROPHENOL - ib tug es muaj zog acid, uas yog sai thiab nquag nkag mus rau hauv pauv tshua. Tus sis ntawm lub hlau ntsev tsim - thiaj hu ua picrates. Cov feem ntau siv ntsev ntawm hmoov txhuas, sodium, hlau thiab poov hlau. Interestingly, picric acid ntsev muaj ntau, uas yuav tsum tau ntxiv mob nyob rau hauv zus tau tej cov mos txwv.

Picric acid thiab heev ntaus ntawv

Nyob rau hauv keeb kwm nws yog tus thawj TRINITROPHENOL zoo heev. Heev zog acid thiab nws ntsev tau pom ib ncig ntawm lub kawg ntawm lub xyoo pua, tab sis siv ntau heev thaum lub sij hawm tsov rog nws pib xwb nyob rau hauv lub 30s ntawm XIX caug xyoo.

Siv trinitrophenol muab ib tug tshiab impetus rau txoj kev loj hlob ntawm cov tub rog technology. Qhov tseeb hais tias picrates thiab picric acid nws tus kheej muaj nuj nqis ntau dua poob siab-puas zog tshaj cov hmoov uas tau siv nyob rau hauv cov hnub.

Lub ncov ntawm lawv tej chaw mus txog xws explosives thaum lub sij hawm ob ntiaj teb rog. Thaum hnub tam sim no, qhov no technology yog yuav luag yeej tsis siv.

Yuav ua li cas kom tau TRINITROPHENOL?

Picric acid tej zaum yuav tau thaum lub sij hawm ncaj nitration ntawm phenol cov tshuaj tiv thaiv uas muaj ntau ntawm nitric acid. Tab sis ua ntej xav txog qhov twg mus yuav nitric acid, nws yog tsim nyog sau cia hais tias tsim txoj kev los yog pikrina picrates heev txaus ntshai. Keeb kwm paub ntau yam tragic leej twg.

Siv picric acid

Nyob rau hauv qhov tseeb TRINITROPHENOL siv tsis tau tsuas yog los mus tsim explosives. Qhov no kev twb kev txuas yog ntau nyob rau hauv lwm yam sectors ntawm kev lag luam. Piv txwv li, pikrin yog ib nrab nyob rau hauv qhov siv thiab ua tej yam dyes.

Cov tshuaj yeeb dej caw tau raug lees paub tias nyob rau hauv cov kev kho mob teb, uas yog tej zaum kuj siv tau raws li ib tug antiseptic.

Nyob rau hauv zus tau tej cov hlau picric acid yog siv raws li ib tug etchant. Nyob rau hauv tshuaj kev lag luam nws yog siv raws li ib lub hauv paus thaum lub sij hawm lub polymerization cov tshuaj tiv thaiv. Los ntawm nws yog npaj raws li pigments rau uas tseg tau histology los yog mus kuaj nyob rau hauv thiaj li yuav kos tus cim rau laboratory tsiaj.
