Potasiuma thiocyanate - heʻawahia waiwai hoʻohana i ka mākau kemika

Potasiuma thiocyanate (i loko o ke kālā no IUPAC nomenclature - potasiuma thiocyanate) - nā pōaka me ka waihoʻoluʻu a me ka ala; ma finely maheleia lilo iā ia keʻokeʻo. Ka waiwai i ka awaawa ono pungent, Ua make. Potasiuma thiocyanate mea nui wailana ma na mea he nui nā'uheheʻe, e like me ka wai, ethanol, a me ka amyl ka waiʻona.

? eaia

Ua hoomakaukauia ke hui wale ma Nine Inch mea, distinguishes ia mai maoli kumu (koko a me kou tuha 'ana o kanaka) - ka'āina pipiʻi. I mea e synthesize i ka potasiuma thiocyanate, pono e hui kākoʻo pāʻoihana o ke'amoniuma thiocyanate a me ka potasiuma hydroxide (e like me ka inoa - potasiuma hydroxide).

Hoʻokolohua Ua lawe mai ma lalo o ka hewa, no ka mea, o ka ammonia hiki i Nine Inch'ā a me kaʻapu kōheoheo; laila, kānana o ka maloko pāʻoihana i evaporated a me ke koena, e haawi nā pōaka o ka makemake waiwai. I ka wā o ka auoiaea huahana i kanahiku pakeneka a me ka lawa'amoniuma thiocyanate maemae hāpana, keia iaoiaeii ka loa ka hoʻokō.

ala i kekahi mea luaipele oka a me ka potasiuma cyanide, akā, e like me ke kaʻina hana no ka makaukau o ka potasiuma thiocyanate mea nō ka mea, no o ke kaʻawahia kiʻekiʻe o ka cyanide.

palapala noi

Pili potasiuma thiocyanate, nā mea loaʻa a pau, a me nā pāʻoihana a me kekahi mau nā hoʻohui like o kekahi mau nāʻoihana. No kekahi laʻana:

• Lole hana.
• Kiʻi Auana.
• Ke aloha hoʻololi kemikala.
• Mākau kemika.

Mau mea o ka i

1. I ka lole hana. potasiuma thiocyanate pāʻoihana ua hoʻohana 'ia no ka etching nā'aʻaʻa, e laʻa me - i noi silika, a me ka lawelawe ana i ka malama i ka loiloi mua waiwai o ka mea.
2. Ma ke aloha hoʻololi kemikala. Mai potasiuma thiocyanate synthesized kekahi ke aloha waiwai, e like me thiourea, he kemikala makeke aila a me ka likeʻole make. I loaa me ke kōkua o nā thiocyanates, e laʻa me - keleawe thiocyanate-2.
3. I ka mākau kemika, potasiuma thiocyanate pāʻoihana ua hoʻohana 'ia no ka manao paa o cations o trivalent hao i loko o ka mea. An illustrative kumu hoʻohālike o ka naoh, i komo ai potasiuma thiocyanate a me ferric koloriside-3, i kapaia o "ke koko o ka wai", i a he pōpolohua-ulaula potasiuma hexacyanoferrate 3; maa inoa - ula koko paakai. kekahi hoʻohana Thiocyanates no ka hookaawale ana i pohihihi ke hooheheeia e like me thorium a me ka lanthanum. Thiocyanate, potasiuma koloriside a me ka jelly ia wa mua kōkua i loko o ka? Iecaianoaaiiie oʻimi hoʻopunipuni koko no ka kinosomok, akā, i kēia iaoia hele ma ke alanui ma muli o ia ka hoʻokomo 'ana i ka manaʻoe kūkulu? Iecaianoaaiiie kiʻi kamepiula o.
4. I ka mahiʻai, mai pāʻoihana loaa Thiocyanates ikaika insecticides. Aia i mau hiki reactions:

• Mua - ka loaa ana kinoea thiocyano ma ka hiʻona potasiuma paakai; Rodan mea he weliweli loa kinoea no nā meaola e noho ana, a ua kākaʻikahi i hoʻohana.
• Lua - mea hoʻoheheʻeʻia potasiuma thiocyanate, kauoha kuu i hydrolysis tsianovodorodnoyʻakika a me'okesaside o ka kūpono waiwai e cyanogen. Cyan - ole emiʻawahia, akā, oi kaumaha kinoea hoʻohālikelike me Rodan, a no ia mea, ua hoʻohana 'ia pinepine i ka insecticide.

Potasiuma thiocyanate mea heʻawahia waiwai ka lethal mahele lāʻau mea e pili ana i 0,9 nā huna o ka waiwai no kilogram o ke kino ke kaumaha ma luna o moʻolelo hoʻomākaukau o ka hui.

loaʻa nui

potasiuma thiocyanate hiki ke kuai ma kekahi Shop Nine Inch, akā, ma ka mea uuku, no ka mai o ke kaʻawahiaʻano kiʻekiʻe. Ka awelika kumukuai o ka mea kemikala - eha rubles no kilogram, kuai ka hapanui kaupalena 'ia nā paona no kanaka.

e malu ai

Manawa i kona kaʻawahia, pono e waiho potasiuma thiocyanate ma kūikawā rula e like me ka palekana rula no ka lawelawe anaʻawahia waiwai:

1. Nā pōaka a me nā pāʻoihana o potasiuma thiocyanate pololei pāpā kino a me ka lahui undesirable ingress o nā pāʻoihana a me ka lehulehu kiʻekiʻe o ke kumu o waiwai i ka ili.
2. I loko nō o ka mea i ka lāʻau meaʻawahia wale ia ana oloko hana me ka waiwai ka pono ma ka laholio Loan Keʻena kapa komo, a me, like me nā mea a pau Nine Inch ma walaʻauʻana maluhia koi.
3. He mea pono e kaʻawale ka mea, mai na keiki a me ka mea e ole i ike i ka technician me ka mea hiki i kaʻawaʻawa loa i hana 'ia me ka lilo ana o reagents, hoʻohana kūpono' ole, a me ka manawa e make.
4. No nonflammable waiwai a me ka pono i ka pilina paʻa i loko o ka lewa, e mea hiki ke kahu ai i ka papaa waiwai i loko o ka pouli. maloo keena mehameha. Pale kiʻekiʻe humidity a me ka pololei Map, e like me ka hiki hiki mai ma muli o ka mea hōʻemi o ka mea kemikala decomposition o kona ke keʻena wahi. No hoi maʻamau NFPA 704 orthorhombic ka lepili i ka kēia mau hōʻailona: 3 0 0 W, kahi 3 (he uliuli lozenge) - kaʻawahia, 0 (no ka ulaula, a yellow) - flammability a me ka reactivity, a me ka W - hoailona no ka AaOIeIOUIeXAOAaIN me ka wai, a ua hookuu make thiocyanicʻakika.

A e hoomanao, Nine Inch ho okolohua - he mea kupaianaha, a me nā hana, akā,ʻaʻole loa haʻalele kaiapuni!
