Asidi Picric: malongosoledwe Concise zinthu

Picric acid - ndi zovuta mankhwala mankhwala omwe ndi nitro otumphukira wa phenol. Mwa njira, pawiri izi amadziwika sayansi "TRINITROPHENOL". Mankhwala palokha ndipo salt zake ntchito monga mabomba.

asidi Picric: chilinganizo ndi thupi katundu

Trinitrophenol ndiyo njira motere:

C6H2 (NO2) 3OH

Mu mawonekedwe woyera, asidi picric ndi olimba, chomwe ndi timibulu mbale ngati. timibulu wotero kapena colorless kapena pang'ono chikasu kulocha. Limatsogolera mfundo za nkhaniyi inali + 122.5 madigiri Celsius.

Trinitrophenol kulawa zowawa kwambiri, ndipo fumbi lake umasokoneza njira za m'mphuno. Yaitali inhalation zinthu zoipa la munthu, chifukwa kumabweretsa poizoni, vuto la impso ndi maonekedwe a matenda a pakhungu. Komanso zinthu kukhudzana osafunika ndi nembanemba wa mucous. Mwachitsanzo, conjunctiva diso pambuyo chikumveka kuti picric asidi fumbi amakhala achikasu.

asidi Picric: mipweya ndi makhalidwe chachikulu

TRINITROPHENOL bwino sungunuka m'madzi, ngakhale kutentha kumawonjezera solubility magawo ukuwonjezeka. Komabe, zosungunulira abwino kwa thunthu ndi benzene ndi methanol, chloroform ndi kafungo kabwino.

asidi Picric ndi amatha kupanga otchedwa eutectic zosakaniza. chakuti mkulu limatsogolera mfundo chimapangitsa mavuto ena luso ndi zipangizo za zipolopolo. Ndipo pamene kulenga osakaniza trinitrokrezolom nitronaphthalene kapena chithunzi akhoza pang'ono yafupika.

Iwo ayenera kukumbukira kuti TRINITROPHENOL - m'malo asidi amphamvu, umene uli mofulumira ndi mwachangu kulowa zochita kuwombola. Mogwirizana zitsulo mchere anapanga - wotchedwa picrates. The salt zambiri ntchito kutsogolera, sodium, chitsulo ndi calcium. N'zochititsa chidwi picric asidi salt ndi womvera, chimene chimafuna chisamaliro owonjezera kupanga zida.

asidi Picric ndi chipangizo zachiwawa

Mu mbiriyakale anali woyamba TRINITROPHENOL ogwira zachiwawa. Zachiwawa katundu acid ndi mchere zake anapeza kumapeto kwa zaka za m'ma chakhumi ndi chisanu ndi chitatu, koma ntchito kwambiri pa nthawi ya nkhondo inayamba yekha mu 30s za m'ma XIX.

Kugwiritsa trinitrophenol anapereka kutsogolera zatsopano chitukuko cha luso asilikali. chakuti picrates ndi picric asidi iyoyomwe kwambiri wamkulu katundu mantha-zowononga kuposa ufa imene ankagwiritsa ntchito mu masiku amenewo.

Pachimake pa kutchuka kwawo anafika mabomba zoterezi pa Nkhondo Yachiwiri ya World. Pa tsiku lino, njira imeneyi ndi pafupifupi konse ntchito.

Momwe TRINITROPHENOL?

asidi Picric akhoza kuwapeza pa nitration mwachindunji phenol anachita ndi woipa mkulu wa asidi nitric. Koma pamaso kuganiza za kumene kugula asidi nitric, ndi Dziwani kuti kupanga ndondomeko kapena pikrina picrates oopsa kwambiri. History amadziwa ofanana zochitika zambiri zomvetsa chisoni.

Ntchito asidi picric

Ndipotu TRINITROPHENOL ntchito osati kulenga mabomba. kugwirizana ambiri kumabungwe ena a makampani. Mwachitsanzo, pikrin ndi mungafike mu kupanga utoto ena.

thunthu wakhala anazindikira zachipatala, amene nthawi zina amagwiritsidwa ntchito ngati antiseptic.

Kupanga zitsulo asidi picric ntchito monga etchant ndi. Makampani mankhwala agwiritsidwe ntchito ngati chothandizira pa za polymerization anachita. Kwa izo kukonzekera monga inki kwa kudetsa histology kapena zitsanzo kuti awonetse nyama zasayansi.
