Fast Red KD Base

Cov tshuaj npe ntawm Fast Red KD Base yog 3-amino-4-methoxybenzoylaniline, ua haujlwm siab azo dye diazo tivthaiv. Nws zoo nkaus li dawb mus rau lub teeb grey crystalline hmoov nrog cov mis molecular C₁₄H₁₄N₂O₂ thiab molecular hnyav 242.28. Nws nthuav tawm qhov sib txawv ntawm qhov sib txawv (154-156 degree). Cov khoom no yog insoluble hauv dej tab sis soluble hauv cov organic solvents xws li DMF thiab glacial acetic acid. Cov tshuaj tsw qab cov amino pawg, pawg methoxy, thiab benzamide pawg hauv nws cov qauv sib sau ua ke txiav txim siab nws cov khoom siv tshuaj lom neeg thiab kev ua haujlwm ntawm daim ntawv thov.

Thaum lub sij hawm dyeing txheej txheem, lub ceev liab KD puag tau hloov dua siab tshiab rau ib tug nquag diazonium ntsev cation nyob rau hauv ib tug tsawg-kub acidic nruab nrab los ntawm kev ua ntawm sodium nitrite. Cov cation no tom qab ntawd nkag mus rau hauv qhov sib txuas cov tshuaj tiv thaiv nrog ua ntej - siv azo dye tivthaiv los ntawm AS series (piv txwv li, AS-OL, AS-BS) los tsim cov pas dej azo insoluble hauv cellulose fibers xws li paj rwb, viscose, thiab linen. Cov xim uas tau tshwm sim los ntawm vivid, ceev ceev xiav-liab mus rau liab liab, nthuav tawm tshwj xeeb ntxuav, rub, thiab lightfastness. Qhov no ua rau nws zoo tagnrho rau dyeing thiab printing workwear fabrics, sab nraum zoov textiles, thiab high{10}}kawg tsev textiles xav tau superior colourfastness.

Tshaj li kev ua haujlwm tseem ceeb hauv kev ua haujlwm ntawm textile dyeing, ceev liab KD lub hauv paus tseem ua haujlwm ua tus thawj coj tseem ceeb rau kev sib txuas siab -kev ua haujlwm organic pigments (xws li qee cov azo condensation pigments) vim nws cov molecular stability thiab chromogenic zog. Nws pom ntau daim ntawv thov nyob rau hauv automotive coatings, industrial inks, thiab engineering yas colouring, xa zoo heev tshav kub kuj thiab migration kuj.

1.4-Methoxy-3-aminobenzoylaniline yog npaj los ntawm reacting 3-aminobenzoylaniline nrog methanol. Cov tshuaj tiv thaiv no tuaj yeem nqa tawm ntawm chav tsev kub, thiab ntau tshaj methanol yuav tsum tau ua raws li cov tshuaj tiv thaiv nruab nrab.
2.Tom qab cov tshuaj tiv thaiv tiav lawm, cov khoom siv tshuaj tiv thaiv yog purified los ntawm crystallization, pom, thiab ziab kom tau siab -purity 4-methoxy-3-aminobenzoylaniline.

4-Methoxy-3-aminobenzoylaniline yog ib qho tseem ceeb dye intermediate uas tuaj yeem siv los ua ke cov dyes nrog cov xim tshwj xeeb thiab cov khoom siv kho qhov muag. Nws kuj tseem tuaj yeem ua tus catalyst lossis reagent hauv cov organic synthesis cov tshuaj tiv thaiv, txhawb cov tshuaj lom neeg tshwj xeeb hauv cov txheej txheem organic synthesis.

Peb muab 24-teev tom qab- kev muag khoom. Rau cov lus nug txog cov khoom lag luam, thov hu rau peb ntawm email lossis xov tooj. Peb muaj ntau tus neeg mob thiab txaus siab rau cov neeg ua haujlwm nrog ntau xyoo ntawm kev muag khoom thiab kev paub txog tshuaj, npaj txhij los pab koj.
