Daim ntawv thov

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

2. Siv los ua raw khoom rau extracting thiab cais pyridine thiab nws homologues

3. Cov txuj lom.

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

5. Feem ntau yog siv los ua cov khoom siv raw hauv kev lag luam, ua cov kuab tshuaj thiab cawv denaturant, tseem siv los ua cov roj hmab, xim, resin thiab corrosion inhibitors, thiab lwm yam.

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

Pob

1 kg / hnab lossis 25 kg / nruas lossis 50 kg / nruas lossis raws li cov neeg siv khoom xav tau.

Txog Kev Thauj Mus Los

1. Peb tuaj yeem muab ntau hom kev thauj mus los raws li peb cov neeg siv khoom xav tau.
2. Rau cov khoom me me, peb tuaj yeem xa nkoj los ntawm huab cua lossis thoob ntiaj teb xa khoom, xws li FedEx, DHL, TNT, EMS, thiab ntau yam kev thauj khoom tshwj xeeb thoob ntiaj teb.
3. Rau ntau qhov ntau, peb tuaj yeem nkoj los ntawm hiav txwv mus rau qhov chaw nres nkoj.
4. Tsis tas li ntawd, 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.

Cia

1. Khaws rau hauv qhov chaw txias, cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C.

2. Nws yuav tsum tau muab cais tawm ntawm oxidants, acids, thiab edible chemicals, thiab tsis txhob sib tov cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua.

3. Nws yog txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim tsim cov nplaim taws.

4. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov ntaub ntawv khaws cia tsim nyog.

Kev ruaj ntseg

1. Tsis muaj decomposition nyob rau hauv ib txwm kub thiab siab. Txwv tsis pub kev sib cuag nrog cov kua qaub, muaj zog oxidants, thiab chloroform. Cov thawv tooj liab yuav tsum tsis txhob siv. Tsis txhob khaws cia nrog cov oxidants muaj zog xws li peroxides thiab nitric acid.

2. Pyridine kuj ruaj khov rau oxidants thiab tsis oxidized los ntawm nitric acid, chromium oxide, poov tshuaj permanganate, thiab lwm yam., yog li nws yuav siv tau raws li ib tug hnyav nyob rau hauv cov tshuaj tiv thaiv oxidation nrog permanganate. Lub luag haujlwm ntawm hydrogen peroxide lossis peracid ua N-oxide (C5H5NO).

3. Nws yog ib qho nyuaj rau pyridine kom tau txais cov tshuaj tiv thaiv electrophilic, thiab Friedel Crafts tsis tshwm sim. Thaum lub sij hawm nitration, qhov kub ntawm 300 ° C yuav tsum tau kom tau 3-nitropyridine, thiab tawm los yog tsawg. Tab sis nws yog nquag mus rau nucleophilic hloov cov tshuaj tiv thaiv. Piv txwv li, nrog sodium amide los tsim 2-aminopyridine. Thaum platinum los yog alkali siv los ua ib qho catalyst los cuam tshuam nrog cov dej hnyav, qhov thib ob hydrogen ntawm pyridine tuaj yeem pauv nrog hnyav hydrogen.
