Daim ntawv thov

1. Siv los ua cov kuab tshuaj organic, analytical reagent, kuj siv hauv cov organic synthesis kev lag luam, chromatography, thiab lwm yam.

2. Siv los ua cov khoom siv raw rau rho tawm thiab sib cais pyridine thiab nws homologes

3. Cov txuj lom yog.

4. Pyridine yog cov khoom siv raw rau cov tshuaj tua kab, tshuaj tua kab, roj hmab Auxilies, thiab textile auxilies.

5. Siv tau ua cov khoom siv raw hauv kev lag luam, raws li kev siv roj hmab thiab cov xim dej caw, muab cov xim pleev xim, khoom siv thiab corrosion inhibitors, thiab lwm yam.

6. Pyridine kuj tseem siv tau los ua tus neeg sawv cev thiab Dyeing tus neeg sawv cev hauv kev lag luam.

Lub thawv

1 kg / hnab los yog 25 kg / nruas lossis 50 kg / nruas lossis raws li cov neeg siv khoom yuav tsum tau ua.

Hais Txog Tsheb Thauj Mus Los

1. Peb tuaj yeem muab ntau hom kev thauj mus los xij raws li peb cov neeg siv khoom xav tau.
2. Rau cov khoom me me, peb tuaj yeem xa khoom los ntawm cov huab cua lossis cov chaw ua haujlwm thoob ntiaj teb, xws li FedEx, TNT, EMS, thiab ntau yam hauv ntiaj teb thauj khoom tshwj xeeb kab.
3. Rau cov ntau ntau, peb tuaj yeem xa nkoj los ntawm hiav txwv mus rau qhov chaw nres nkoj uas tsim qauv.
4. Txuas ntxiv, peb tuaj yeem muab cov kev pabcuam tshwj xeeb raws li peb cov neeg siv khoom xav tau thiab cov khoom ntawm lawv cov khoom.

Chaw ntim khoom

1. Khaws rau hauv qhov chaw txias, tshuab ua kom muaj zog. Tseg deb ntawm hluav taws thiab cov khoom cua sov. Qhov kub yuav tsum tsis pub tshaj 30 ° C.

2. Nws yuav tsum tau muab cais cais los ntawm oxidants, acids, thiab cov tshuaj muaj khoom siv, thiab zam kom tsis txhob sib xyaw. Siv tawg-pov thawj teeb pom kev zoo thiab cov chaw tua hluav taws xob.

3. Nws yog txwv tsis pub siv cov cuab yeej siv neeg thiab cov cuab yeej uas tau yooj yim tsim cov chaw ua haujlwm.

4. Cov cheeb tsam cia yuav tsum tau nruab nrog cov khoom siv kub ceev thiab cov ntaub ntawv tshwj xeeb.

Ruaj khov

1. Tsis muaj kev txiav txim siab nyob rau hauv qhov kub thiab txias thiab siab. Txwv tsis pub muaj kev sib chwv nrog cov kua qaub, oxidants muaj zog, thiab chloroform. Cov khoom ntim khoom ntiav yuav tsum tsis txhob siv. Tsis txhob khaws nws nrog oxidants muaj zog xws li pom thiab nitric acid.

2. Pyridine yog qhov ruaj ntseg rau oxidants thiab tsis yog oxidized los ntawm nitric acid, potassium permanganate, thiab lwm yam yuav siv tau los ua cov tshuaj tiv thaiv oxidation nrog permanganate. Lub luag haujlwm ntawm hydrogen peroxide lossis peracid ua n-oxide (C5h5NO).

3. Nws yog qhov nyuaj rau pyridine kom yauv hluav taws xob hloov pauv kev xav, tsis yog friedel Crafts cov tshuaj tiv thaiv tshwm sim. Thaum nitration, qhov kub ntawm 300 ° C yog yuav tsum tau 3-nitropyridine, thiab cov txiaj ntsig yog tsawg. Tab sis nws yog nquag rau nucleophilic hloov cov kev coj ua. Piv txwv li, nrog sodium nyob hauv tsev kom tsim 2-aminopyridine. Thaum Platinum lossis Alkali tau siv los ua kev sib cuam tshuam nrog cov dej hnyav, lub tsev thib ob hydrogen ntawm pyridine tuaj yeem sib pauv nrog cov hydrogen ntau.
