Kushandiswa kweSodium Cyanide muDye Indasitiri

Sodium cyanide, kemikari inosanganiswa ine fomula NaCN, inoita basa rakakosha mu Dye Industry. Inoshanda sechinhu chakakosha mukugadzirwa kwemavara akasiyana-siyana edhayi, zvichipa kune inoyevedza uye ine ruvara nyika yemachira, kudhinda, uye mamwe minda ine hukama.

1. Kusanganiswa kweDyees dzakasiyana-siyana

1.1 Yellow Dyes

Sodium cyanide inobatanidzwa mukugadzirwa kweYero 139 uye Yero 150. Mukuita kwemakemikari pakugadzira dhayi yeyero, Sodium Cyanide anotora chikamu muzvirongwa zvinobatsira kuumba chaiwo mamorekuru zvimiro. Semuyenzaniso, inogona kuita pamwe nemamwe organic compounds kuunza cyanide mapoka (-CN), ayo akakosha kuti chromophore (chikamu chemorekuru chinokonzera ruvara rwayo) kuumbwa. Aya madhayi eyero anoshandiswa zvakanyanya mukudhaya machira, kunyanya kugadzira mavara eyero anopenya uye akajeka pamachira akadai sedonje, sirika, uye polyester.

1.2 Indigo

Indigo, imwe yedhayi dzinonyanya kuzivikanwa uye dzinoshandiswa zvakanyanya munhoroondo yese, ine chikwereti chayo chekubatanidza sodium cyanide. Iyo synthesis nzira ye indigo inowanzobatanidza maitiro uko Sodium cyanide inopindirana nemidziyo yekutanga yakakodzera, kazhinji kuburikidza nenhevedzano ye condensation uye cyclization maitiro. Iro cyanide boka rakaunzwa nesodium cyanide inosanganisirwa mune indigo molecule chimiro, iyo inopa indigo hunhu hwayo hwakadzika bhuruu ruvara. Indigo inonyanya kushandiswa muindasitiri yedenim, ichipa jeans yavo yemhando yebhuruu mumvuri.

1.3 Phthalocyanine Blue (Hu Lan)

Phthalocyanine yebhuruu, inowanzozivikanwa seHu Lan, imwe dhayi yakakosha yakagadzirwa nerubatsiro rwesodium cyanide. Iyo synthesis yephthalocyanine - yakavakirwa dhayi inzira yakaoma. Sodium cyanide inoshandiswa kufambisa maitiro anotungamira mukuumbwa kweiyo hombe, planar phthalocyanine mhete chimiro. Kuvapo kwe cyanide - mapoka anotorwa mumamorekuru anokanganisa maitiro emagetsi edhayi, achisarudza ruvara rwebhuruu. Phthalocyanine madhayi ebhuruu anokosheswa zvakanyanya nekureruka kwawo uye anoshandiswa mumhando dzakasiyana siyana dzekushandisa, kusanganisira machira emotokari, mavara epurasitiki, uye emhando yepamusoro-yekudhinda ingi.

1.4 Fluorescent Whitening Agent VBL

Fluorescent Whitening Agent VBL inoshandiswa zvakanyanya kuwedzera kuchena uye kupenya kwemachira nemapepa. Sodium cyanide chinhu chakakosha reagent mukuumbwa kwayo. Munguva yekugadzira, sodium cyanide inotora chikamu mukuita kunovaka iyo chaiyo molecular chimiro che fluorescent whitening agent. Mapoka ane hukama necyanide akakosha pakugona kwemumiririri kutora ultraviolet mwenje uye kuiburitsa zvakare seinooneka yebhuruu - chena mwenje, zvinobudirira kubhadhara iyo yero tint yezvinhu uye kuita kuti iite seyakachena.

1.5 Disperse Turquoise Blue GL

Disperse Turquoise Blue GL dhayi ine mukurumbira yemafibhi ekugadzira akadai sepolyester. Sodium cyanide inoshandiswa mukugadzira kugadzira anodiwa emakemikari bond uye mamorekuru marongero. Nekuita nezvimwe zvinhu zvakasikwa, boka re cyanide kubva ku sodium cyanide rinova chikamu chakakosha chemorekuru wedhayi, zvichibatsira kune yayo turquoise - yebhuruu ruvara. Iri dhayi rakanyatsokodzera kudhaya machira epolyester nekuda kwekunaka kwayo kwekuparadzira zvinhu mune isiri-aqueous media.

1.6 Bhuruu 60

Bhuruu 60. kufanana nemamwe madhayi akawanda, zvinobatsira kubva pakushandiswa kwe sodium cyanide mukugadzirwa kwayo. Maitiro emakemikari anosanganisira sodium cyanide anobatsira kugadzira iyo yakasarudzika mamorekuru iyo inopa dhayi ruvara rwayo rwebhuruu rwakasiyana. Inoshandiswa mumhando dzakasiyana siyana dzekudhaya, kusanganisira dziri mumaindasitiri emucheka nekudhinda, uko kunodiwa mumvuri wayo webhuruu.

2. Basa muDye Synthesis Reactions

Sodium cyanide inoshanda munzira dzakawanda panguva Dye SynthesisChekutanga, inowanzo shanda se nucleophile. Mukuita kwe organic synthesis, cyanide ion (CN⁻) inogona kurwisa nzvimbo dze electrophilic mune mamwe mamorekuru. Semuenzaniso, mukugadzirwa kwe indigo, cyanide ion inogona kurwisa a kabhoniyl - ine musanganiswa. Kurwiswa uku kwe nucleophilic kunotanga maitiro akasiyana-siyana ayo pakupedzisira anotungamira pakuumbwa kwe indigo molecule.

Chechipiri, sodium cyanide inogona kubatanidzwa mukuita condensation. Mukuumbwa kwephthalocyanine yebhuruu, cyanide - ine makomisheni inobata pamwe nemamwe precursors kuburikidza ne condensation reactions, uko mamorekuru madiki anobviswa, uye makuru, akaomarara maumbirwo anoumbwa. Mapoka ecyanide anobatsira mukukura kwephthalocyanine ring system.

3. Mafungiro Ezvakatipoteredza uye Kuchengetedzwa

Nepo sodium cyanide yakakosha muindasitiri yedhayi, kushandiswa kwayo kunouyawo nekukosha kwezvakatipoteredza uye kuchengetedza kunetseka. Sodium cyanide ine chepfu zvakanyanya. Mukugadzira dhayi, maprotocol akasimba ekuchengetedza anofanirwa kunge aripo kudzivirira chero kuvuza kana kuratidzwa kune vashandi. Kubata zvakanaka, kuchengetedza, uye kutakura sodium cyanide kwakakosha.

Kubva pamaonero ezvakatipoteredza, chero mvura yetsvina inogadzirwa panguva yedhayi synthesis process ine sodium cyanide kana maitiro ayo ne-zvigadzirwa zvinofanirwa kubatwa nemazvo. Kana ikaburitswa isina kurapwa, cyanide - ine tsvina yemvura inogona kukuvadza zvakanyanya kuhupenyu hwemumvura. Tekinoroji dzakadai semakemikari oxidation, biological kurapwa, uye ion - kuchinjana kunowanzo shandiswa kubvisa cyanide kubva mumaindasitiri emarara.

Mukupedzisa, sodium cyanide chinhu chakakosha muindasitiri yedhayi, ichigonesa kugadzirwa kweakasiyana siyana ane mavara uye anobatsira madhayi. Nekudaro, njodzi dzayo dzinogona kuitika dzinofanirwa kubatwa nemazvo kuti ive nechokwadi chekuchengetedzwa kwevashandi uye kuchengetedzwa kwenharaunda. Sezvo indasitiri iri kuramba ichishanduka, kuedza kungangove kwakanangana nekuvandudza maitiro akasimba uye akachengeteka ayo achiri kushandisa mabhenefiti e sodium cyanide mudhayi synthesis.
