Waikawa Picric: matū whakaahuatanga poto

Picric Waikawa - ko te uaua taonga matū i te mea he pärönaki nitro o phenol. E te ara, mohiotia tenei pūhui te i roto i te pūtaiao rite "TRINITROPHENOL". Taonga iho me ona tai e whakamahia rite explosives.

waikawa Picric: tātai me ngā āhuatanga ōkiko

Trinitrophenol tātai ko e whai ake:

C6H2 (NO2) 3OH

I roto i te puka parakore, ko te totoka, e ngā o tioata rihi-rite waikawa picric. kia taua tioata rānei taekore i te kauruku kowhai iti ranei. Ko te ira whakakoero o tenei rauemi i + 122.5 degrees.

Trinitrophenol pangia e kawa rawa, a ka irritates tona puehu i te mau irava nasal. Roa inhalation o matū kino ki te rauropi tangata, mai i arata'i te reira ki poisoning, kino täkihi me te ahua o mate kiri. Matū me te whakapā houhou ki te kiriuhi mucous. Tauira, kanohi kirikamo i muri i patu i te reira puehu waikawa picric riro kōwhai.

waikawa Picric: hanganga matū me ngā āhuatanga matua

TRINITROPHENOL ruarua wairewa i roto i te wai, ahakoa faarahi te pāmahana te piki tawhā memehatanga. Heoi, ko te whakarewa pai mo te taonga he benzene me methanol, chloroform me te hauwaiwaro.

Ko te ahei o hanga nga ranunga eutectic pera-ka karanga ano hoki waikawa Picric. Ko te take i te ira whakakoero tiketike hanga te tahi mau fifi hangarau ki te taputapu o te matā. A ka hanga ranunga trinitrokrezolom nitronaphthalene ranei kia wāhanga iti ai te ahua.

Me mahara hoki käore te reira e TRINITROPHENOL - he kaua waikawa kaha, i te mea tomo tere, me te kaha ki tauhohe utu. Ko te pāhekoheko o te tote whakarewa i hanga - na ka karanga picrates. Ko te tai tino whakamahia nuitia o mata, konutai, rino, me te konupūmā. Te mea faahiahia, e atu tairongo tai waikawa picric, e titau tiaki anō i roto i te hanga o te matā.

waikawa Picric me te pūrere taikaha

I roto i te hītori, ko reira te TRINITROPHENOL whai hua tuatahi taikaha. Kua kitea waikawa āhuatanga taikaha me ona tai huri noa te mutunga o te rau tau tekau ma waru, engari whakamahia ngā i roto i te pakanga tīmata reira anake i roto i te 30raa o te rau XIX.

hoatu Mā te trinitrophenol he hiringa hou ki te whanaketanga o te hangarau hōia. Ko te meka e picrates me picric waikawa ano he āhuatanga tino nui ru-kino atu i te paura i i whakamahia i roto i aua ra.

tae te tihi o ratou rongonui taua explosives i roto i te Pakanga Tuarua o te Ao. I ra reira, Kei te tata kore whakamahia tenei hangarau.

Me pēhea te ki te tiki TRINITROPHENOL?

kia whiwhi waikawa Picric i roto i te nitration tika o te phenol tauhohe ki nohanga tiketike o te waikawa hauota. Otiia i mua i whakaaro e pā ana ki te wahi ki te hoko te waikawa hauota, he reira ia tapao e te tukanga ahumahi picrates pikrina ranei tino kino. History mohio maha mahinga fakamamahi e pā ana.

Mā te waikawa picric

I roto i te meka TRINITROPHENOL whakamahia kore anake ki te waihanga explosives. he whānui i roto i te tahi atu rāngai o te ahumahi tenei hononga. Hei tauira, ko te takawaenga i roto i te hanga o etahi waikano pikrin.

Kua mohio te rawa kua i roto i te mara hauora, e te tahi mau taime whakamahia hei rongoā.

I roto i te hanga o te konganuku whakamahia waikawa picric te rite te etchant. I roto i te ahumahi matū te whakamahia te reira rite te whakakōkī i roto i te tauhohe polymerization. Mai i Kua rite te reira rite uhi mō te poke histology tauira ranei i roto i te tikanga ki te tohu i te kararehe taiwhanga.
