Fa'aaogāga

1. Faʻaaogaina e avea o se solvent organic, analytical reagent, faʻaaogaina foi i alamanuia faʻapipiʻi faʻasolosolo, chromatography, ma isi.

2. Faʻaaogaina e avea o se mea mataʻutia mo le suʻeina ma le tuʻueseese o le pyridine ma ona homologues

3. Mea manogi lelei.

4. O le Pyridine o se mea mataʻutia mo vailaʻau faʻamaʻi, iniseti, paʻu fesoasoani, ma ie fesoasoani.

5. Faʻaaogaina faʻapitoa e avea o se mea mataʻutia i totonu o le alamanuia, e pei o se solvent ma le ava malosi, faʻaaogaina foi i le gaosiga o le paʻu, vali, resini ma inhibitors corrosion, ma isi.

6. E mafai foʻi ona faʻaaogaina le Pyridine e avea o se denaturant ma le vali vali i totonu o pisinisi.

afifi

1 kilokalama / taga poʻo 25 kilokalama / paʻu poʻo 50 kilokalama / paʻu poʻo e tusa ai ma manaoga o tagata faʻatau.

E uiga i Femalagaiga

1. E mafai ona matou ofoina atu ituaiga eseese o felauaiga e faʻatatau i manaʻoga oa tatou tagata faʻatau.
2. Mo vaega laiti, e mafai ona matou vaʻaia i luga o le ea poʻo faʻasalalauga faavaomalo, e pei o FedEx, DHL, TNT, EMS, ma laina faʻapitoa felauaiga faavaomalo eseese.
3. Mo le tele o aofaʻi, e mafai ona matou vaʻavaʻai i le sami i se uafu faʻatulagaina.
4. E le gata i lea, e mafai ona matou tuʻuina atu auaunaga faʻapitoa e tusa ai ma manaʻoga a matou tagata faʻatau ma meatotino o latou oloa.

Teuina

1. Teu i totonu o se faleteuoloa malulu ma ea. Taofi mai le afi ma le vevela. Ole vevela ole teuina e le tatau ona sili atu ile 30°C.

2. E tatau ona teuina ese mai oxidants, acids, ma vailaau taumafa, ma aloese mai le teuina fefiloi. Fa'aaogā moli e fa'asao pa ma mea e fa'alelei ai.

3. E fa'asaina le fa'aogaina o masini fa'ainisinia ma mea faigaluega e faigofie ona maua ai aloiafi.

4. O le nofoaga e teu ai e tatau ona faʻapipiʻiina i masini faʻafuaseʻi togafitiga faʻafuaseʻi ma mea talafeagai e teu ai.

Maumau

1. Leai se pala i lalo o le vevela masani ma le mamafa. Fa'asa le fa'afeso'ota'i ma vaila'au, vaila'au malolosi, ma chloroform. E le tatau ona fa'aogaina pusa kopa. Aloese mai le teuina i vailaʻau malolosi e pei ole peroxides ma le nitric acid.

2. Pyridine e fai si mautu i oxidants ma e le oxidized e nitric acid, chromium oxide, potassium permanganate, ma isi, o lea e mafai ona faaaoga o se solvent i le tali oxidation ma permanganate. Ole matafaioi ole hydrogen peroxide po'o le peracid e avea ma N-oxide (C5H5NO).

3. E faigata mo pyridine ona faʻaogaina le electrophilic substitution reaction, e le tupu foi le tali a Friedel Crafts. I le taimi o le faʻamaʻiina, e manaʻomia le maualuga o le vevela o le 300 ° C e maua ai le 3-nitropyridine, ma e maualalo le fua. Ae e faigofie ile nucleophilic substitution reaction. Mo se faʻataʻitaʻiga, faʻatasi ai ma le sodium amide e maua ai le 2-aminopyridine. A faʻaaogaina le platinum poʻo le alkali e fai ma faʻamalosi e fegalegaleai ma vai mamafa, o le hydrogen lona lua o le pyridine e mafai ona fesuiaʻi ma le mamafa mamafa.
