Daim Ntawv Thov Sodium Cyanide hauv Kev Lag Luam Dye

Sodium cyanide , ib qho tshuaj lom neeg uas muaj cov mis NaCN, ua lub luag haujlwm tseem ceeb hauv Kev Lag Luam Xim . Nws ua haujlwm ua cov khoom siv tseem ceeb hauv kev tsim ntau yam xim, pab txhawb rau lub ntiaj teb ci ntsa iab thiab muaj yeeb yuj ntawm cov ntaub, kev luam ntawv, thiab lwm yam kev lag luam.

1. Synthesis ntawm ntau yam Dyes

1.1 Yellow Dyes

Sodium cyanide koom nrog kev tsim cov xim daj 139 thiab xim daj 150. Hauv cov tshuaj lom neeg rau kev tsim cov xim daj no, Sodium Cyanide koom nrog cov txheej txheem uas pab tsim cov qauv molecular tshwj xeeb. Piv txwv li, nws yuav teb nrog lwm cov organic compounds los qhia cov pab pawg cyanide (-CN), uas yog qhov tseem ceeb rau chromophore (ib feem ntawm cov molecule uas yog lub luag haujlwm rau nws cov xim). Cov xim daj no pom kev siv dav hauv kev zas xim ntaub, tshwj xeeb tshaj yog rau kev tsim cov xim daj ci thiab ci ntsa iab ntawm cov ntaub xws li paj rwb, txhob lo lo ntxhuav, thiab polyester.

1.2 Indigo ib

Indigo, yog ib qho ntawm cov xim uas paub zoo tshaj plaws thiab siv dav thoob plaws keeb kwm, kuj muaj nws cov khoom tsim los ntawm sodium cyanide . Txoj kev tsim cov indigo feem ntau muaj cov tshuaj tiv thaiv uas Sodium cyanide ua rau cov khoom pib tsim nyog, feem ntau yog los ntawm ntau yam kev sib xyaw ua ke thiab kev sib hloov pauv. Pawg cyanide uas sodium cyanide tau qhia tau koom nrog rau hauv cov qauv ntawm indigo, uas ua rau indigo muaj xim xiav tob. Indigo feem ntau siv rau hauv kev lag luam denim, ua rau cov ris tsho jeans muaj xim xiav zoo nkauj.

1.3 Phthalocyanine Xiav (Hu Lan)

Phthalocyanine xiav, feem ntau hu ua Hu Lan, yog lwm qhov tseem ceeb dye synthesized nrog kev pab ntawm sodium cyanide. Lub synthesis ntawm phthalocyanine - raws li dyes yog ib tug complex txheej txheem. Sodium cyanide yog siv los pab txhawb cov kev cuam tshuam uas ua rau kev tsim ntawm lub nplhaib loj, planar phthalocyanine nplhaib. Lub xub ntiag ntawm cyanide - muab tau los ntawm pawg hauv cov molecule cuam tshuam cov khoom siv hluav taws xob ntawm cov xim, txiav txim siab nws cov xim xiav. Phthalocyanine xiav dyes muaj nuj nqis heev rau lawv qhov zoo tshaj plaws lightfastness thiab siv ntau yam kev siv, nrog rau cov tsheb coatings, yas colouring, thiab high-zoo printing inks.

1.4 Fluorescent Whitening Agent VBL

Fluorescent Whitening Agent VBL yog dav siv los txhim kho cov xim dawb thiab ci ntsa iab ntawm textiles thiab ntawv. Sodium cyanide yog ib qho tseem ceeb reagent nyob rau hauv nws cov synthesis. Thaum lub sij hawm tsim cov txheej txheem, sodium cyanide koom nrog cov tshuaj tiv thaiv uas tsim cov qauv molecular tshwj xeeb ntawm fluorescent whitening agent. Cov cyanide - cov pab pawg muaj feem cuam tshuam yog qhov tseem ceeb rau tus neeg sawv cev lub peev xwm nqus ultraviolet lub teeb thiab rov tso tawm nws li pom xiav - lub teeb dawb, zoo them nyiaj rau cov xim daj ntawm cov ntaub ntawv thiab ua rau lawv pom cov xim dawb.

1.5 Disperse Turquoise Xiav GL

Disperse Turquoise Blue GL yog cov xim nrov rau cov hluavtaws fibers xws li polyester. Sodium cyanide yog siv rau hauv kev sib txuas los tsim cov tshuaj lom neeg tsim nyog thiab kev npaj molecular. Los ntawm reacting nrog lwm cov organic tshuaj, pawg cyanide los ntawm sodium cyanide los ua ib feem ntawm cov xim molecule, pab rau nws turquoise - xiav xim. Cov dyeing no yog tsim nyog rau dyeing polyester fabrics vim nws cov khoom zoo dispersion nyob rau hauv non-aqueous media.

1.6 Xiav 60

Xiav 60. zoo li ntau lwm yam dyes, tau txais txiaj ntsig los ntawm kev siv sodium cyanide hauv nws cov synthesis. Cov tshuaj lom neeg muaj xws li sodium cyanide pab tsim cov qauv molecular tshwj xeeb uas muab cov xim xim xiav sib txawv. Nws yog siv nyob rau hauv ntau yam dyeing daim ntaub ntawv, nrog rau cov nyob rau hauv lub textile thiab luam ntawv industries, qhov twg nws tshwj xeeb ntxoov xiav yog xav tau.

2. Lub luag haujlwm hauv Dye Synthesis Reactions

Sodium cyanide ua haujlwm ntau txoj hauv kev thaum lub sijhawm Dye Synthesis . Ua ntej, nws feem ntau ua haujlwm ua tus nucleophile. Hauv cov tshuaj tiv thaiv organic synthesis, cov cyanide ion (CN⁻) tuaj yeem tawm tsam cov chaw electrophilic hauv lwm cov molecules. Piv txwv li, hauv kev tsim cov indigo, cov cyanide ion tuaj yeem tawm tsam cov tshuaj Carbon yl-muaj. Qhov kev tawm tsam nucleophilic no pib ua ntau yam kev tawm tsam uas thaum kawg ua rau muaj cov molecule indigo.

Qhov thib ob, sodium cyanide tuaj yeem koom nrog hauv cov tshuaj tiv thaiv condensation. Nyob rau hauv cov synthesis ntawm phthalocyanine xiav, cyanide - muaj cov tebchaw react nrog rau lwm cov precursors los ntawm condensation tshua, qhov twg me me molecules raug tshem tawm, thiab loj, ntau complex qauv tsim. Cov pab pawg cyanide pab txhawb kev loj hlob ntawm phthalocyanine nplhaib system.

3. Kev xav txog ib puag ncig thiab kev nyab xeeb

Txawm hais tias sodium cyanide yog qhov tseem ceeb hauv kev lag luam dyeing, nws siv kuj los nrog kev txhawj xeeb txog ib puag ncig thiab kev nyab xeeb. Sodium cyanide yog tshuaj lom heev. Hauv kev tsim cov tshuaj zas xim, cov txheej txheem kev nyab xeeb nruj yuav tsum nyob rau hauv qhov chaw kom tiv thaiv kom tsis txhob muaj kev cuam tshuam los yog cuam tshuam rau cov neeg ua haujlwm. Kev tuav kom zoo, khaws cia, thiab kev thauj mus los ntawm sodium cyanide yog qhov tseem ceeb.

Los ntawm ib puag ncig kev xav, txhua yam dej khib nyiab tsim thaum lub sij hawm dye synthesis txheej txheem uas muaj sodium cyanide los yog nws cov tshuaj tiv thaiv los ntawm - cov khoom yuav tsum tau ua tib zoo kho. Yog tias tso tawm tsis kho, cyanide - muaj cov dej khib nyiab tuaj yeem ua rau muaj kev phom sij heev rau cov dej hauv dej. Cov thev naus laus zis xws li tshuaj oxidation, kev kho mob lom neeg, thiab ion - pauv feem ntau yog ua haujlwm los tshem tawm cyanide los ntawm cov dej khib nyiab.

Hauv kev xaus, sodium cyanide yog ib qho tseem ceeb hauv kev lag luam dyeing, ua kom muaj ntau yam ntawm cov xim zoo nkauj thiab muaj txiaj ntsig zoo. Txawm li cas los xij, nws cov kev phom sij yuav tsum tau tswj xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab kev tiv thaiv ib puag ncig. Raws li kev lag luam txuas ntxiv mus ntxiv, kev siv zog yuav tsom mus rau kev tsim kho kom ruaj khov thiab muaj kev nyab xeeb dua cov txheej txheem uas tseem siv cov txiaj ntsig ntawm sodium cyanide hauv dye synthesis.
