Isicelo

1. Isetshenziswa njenge-solvent ephilayo, i-reagent yokuhlaziya, futhi esetshenziswa embonini ye-organic synthesis, i-chromatography, njll.

2. Isetshenziswa njengempahla eluhlaza yokukhipha nokuhlukanisa i-pyridine nama-homologues ayo

3. Izinongo ezidliwayo.

4. I-Pyridine iyimpahla engavuthiwe yama-herbicides, izibulala-zinambuzane, izinsiza zenjoloba, kanye nezinsiza zendwangu.

5. Ikakhulukazi esetshenziswa njengento eluhlaza embonini, njenge-solvent kanye ne-denaturant yotshwala, futhi isetshenziselwa ukukhiqizwa kwerabha, upende, i-resin kanye ne-corrosion inhibitors, njll.

6. I-Pyridine ingasetshenziswa futhi njenge-denaturant kanye ne-ejenti yokudaya embonini.

Iphakheji

1 kg/isikhwama noma 25 kg/isigubhu noma 50 kg/isigubhu noma ngokwezidingo zamakhasimende.

Isikhathi sokuthumela

1,Inani: 1-1000 kg, zingakapheli izinsuku ezi-3 zokusebenza ngemuva kokuthola izinkokhelo

9, Ngaphandle kwalokho, ngezinye izikhathi siyayemukela i-Bitcoin.

Isitoreji

1. Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C.

2. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-acids, namakhemikhali adliwayo, futhi igweme ukugcinwa okuxubile. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.

3. Akuvunyelwe ukusebenzisa imishini namathuluzi akhiqiza kalula izinhlansi.

4. Indawo yokugcina kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.

Ukuzinza

1. Akukho ukubola ngaphansi kwezinga lokushisa elivamile nokucindezela. Vimbela ukuthintana nama-acids, ama-oxidants aqinile, ne-chloroform. Iziqukathi zethusi akufanele zisetshenziswe. Gwema ukuyibeka ngezixube ezinamandla njengama-peroxides ne-nitric acid.

2. I-Pyridine izinzile uma kuqhathaniswa nama-oxidants futhi ayifakwa i-oxidized nge-nitric acid, i-chromium oxide, i-potassium permanganate, njll., ngakho-ke ingasetshenziswa njenge-solvent ekuphenduleni kwe-oxidation nge-permanganate. Indima ye-hydrogen peroxide noma i-peracid iba yi-N-oxide (C5H5NO).

3. Kunzima ukuthi i-pyridine ibhekane ne-electrophilic substitution reaction, futhi ukusabela kwe-Friedel Crafts akwenzeki. Ngesikhathi se-nitration, izinga lokushisa eliphezulu lika-300 ° C liyadingeka ukuze uthole i-3-nitropyridine, futhi isivuno sincane. Kodwa ithambekele ekuphenduleni kwe-nucleophilic substitution. Isibonelo, nge-sodium amide ukukhiqiza i-2-aminopyridine. Lapho i-platinum noma i-alkali isetshenziswa njenge-catalyst yokusebenzisana namanzi anzima, i-hydrogen yesibili ye-pyridine ingashintshwa nge-hydrogen enzima.
