Synthetic1-amino-2-naphthol-4-sulfonic acid: 1 amino 2 naphthol 4 sulfonic acid tau npaj los ntawm naphthol los ntawm nitrosation, ntxiv thiab sulfonation nyob rau hauv lub xub ntiag ntawm dej cawv tov hnyav. Qhov cuam tshuam ntawm cov khoom siv raw, sib xyaw hnyav piv, lub sijhawm tshuaj tiv thaiv, qhov ntsuas kub thiab qhov pom ntawm cov tshuaj tiv thaiv tau tshawb xyuas, thiab cov txheej txheem zoo tau txiav txim siab Nitrification tej yam kev mob: n (phenol): n (sodium nitrite): n (sulfuric acid) =1: 1:05, nrog 10 g Naphthol meter, 15ml ntawm cov organic solvent isopropanol, ratio ntawm mixed solvent V (dej): V (isopropanol)=(1 ~ 15): 1 Lim thiab ntxuav Cov khoom siv tom qab nitrosation Lub sij hawm ntxiv cov tshuaj tiv thaiv yog tswj ntawm 6h, n (phenol): n (sodium bisulfite) =1: 2, lub sij hawm tshuaj tiv thaiv iodization yog 6h, thiab qhov kub ntawm 50 ~ 60 degree Raws li cov xwm txheej no, yield mus txog 72.1%.

1 amino 2 naphthol 4 sulfonic acid yog cov organic compound nrog ntau yam kev siv, thiab nws cov txheej txheem synthesis muaj ntau haiv neeg.

Txoj Kev 1:

Txoj kev no siv cov amino naphthol sulfonic acid ua raw khoom thiab txais yuav peb-kauj ruam cov tshuaj tiv thaiv sulfonation, txo, thiab amination los ua ke 1 amino 2 naphthol 4 sulfonic acid.

Cov kauj ruam tshwj xeeb yog raws li nram no:

1. Sulfonation: Ntxiv 1-nitro-2-naphthol-4-sulfonic acid rau concentrated sulfuric acid, kub rau 80-90 degree rau sulfonation cov tshuaj tiv thaiv kom tau txais 4-nitro{{ 6}}naphthenesulfonic acid.

TSIS MUAJ₂-1 NAPH-4-SO₃H + 3H₂YOG₄→ NO₂-1 NAPH-4-SO₃H + H₂O

2. Kev txo qis: Ntxiv qhov tsim nyog ntawm tus neeg sawv cev txo qis xws li Na₂S₂O₄lub SnCl₂kom dilute sulfuric acid kom txo tau 4-nitro-1-naphthalene sulfonic acid kom tau txais 4-amino-1-naphthalene sulfonic acid.

TSIS MUAJ₂-1 NAPH-4-SO₃H + 4H₂O + Na₂S₂O₄→ NH₂-1 NAPH-4-SO₃H + Na₂YOG₄

3. Ammoniation: Ntxiv qhov tsim nyog ntawm cov kua ammonia thiab dej ammonia rau cov khoom txo qis saum toj no, thiab nias rau hauv cov hlab ntsha siab txog li 3MPa rau amination cov tshuaj tiv thaiv kom tau 1 amino 2 naphthol 4 sulfonic acid.

NH₂-1-NAPH-4-SO₃H + NH₃ + 2NH₄OH → C₁₀H₉TSIS MUAJ₄S

Qhov tsis zoo ntawm txoj kev no yog: vim yog siv cov concentrated sulfuric acid thiab txo tus neeg sawv cev ntau, muaj ntau cov khoom lag luam, kev ua qias tuaj ib puag ncig yog qhov tseem ceeb, cov txheej txheem ntws tau ntev, thiab cov khoom siv corrosion yog qhov hnyav, ua rau ntau dua. tus nqi.

Txoj Kev 2:

Txoj kev no siv 2-naphthol ua cov khoom siv raw los ua ke 1 amino 2 naphthol 4 sulfonic acid los ntawm ob-kauj ruam cov tshuaj tiv thaiv sulfonation thiab amination.

Cov kauj ruam tshwj xeeb yog raws li nram no:

1. Sulfonation: Sib tov 2-naphthol thiab concentrated sulfuric acid tusyees nyob rau hauv muaj zog stirring, tshav kub mus rau 80-90 degree rau sulfonation cov tshuaj tiv thaiv, thiab tau txais 4-hydroxy-1-naphthalene sulfonic acid.

C₁₀H₈O + H₂YOG₄ → C₁₀H₈O₄S

2. Ammoniation: Ntxiv qhov tsim nyog ntawm cov kua ammonia thiab dej ammonia rau cov khoom sulfonation saum toj no, thiab nias rau hauv cov hlab ntsha siab txog li 3MPa rau amination cov tshuaj tiv thaiv kom tau 1 amino 2 naphthol 4 sulfonic acid.

C₁₀H₈O₄S + NH₃ + 2NH₄OH → C₁₀H₉TSIS MUAJ₄S

Qhov zoo ntawm txoj kev no yog: simplifying cov txheej txheem ntws thiab txo cov nqi tsim khoom; Cov khoom siv raw khoom siv yog cov khoom siv thiab yooj yim los lis; Cov byproducts yog yooj yim cais thiab kho; Cov yield thiab purity kuj siab. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev tswj xyuas qhov kub thiab txias, nrog rau qhov yuav tsum tau kho cov pa khib nyiab thiab kua kom tsis txhob muaj kuab paug ib puag ncig.

Nws yuav tsum raug sau tseg tias cov txheej txheem synthesis tau hais los saum no tsuas yog cov piv txwv xwb, thiab cov txheej txheem synthesis tshwj xeeb yuav txawv nyob ntawm cov txheej txheem sib txawv, cov khoom siv raw, thiab cov khoom siv. Hauv cov txheej txheem tsim khoom tiag tiag, nws yog ib qho tsim nyog los xaiv txoj kev tsim nyog raws li qhov xwm txheej tiag tiag los ua ke1-Amino-2-naphthol-4-sulfonic acid. Nyob rau tib lub sijhawm, nws yuav tsum tau ua tib zoo saib xyuas cov teeb meem kev nyab xeeb thiab kev tiv thaiv ib puag ncig, nruj me ntsis ua raws li cov txheej txheem kev ua haujlwm rau kev tsim khoom, thiab zam kom tsis txhob muaj xwm txheej thiab ib puag ncig muaj kuab lom.
