Omaka bomkhiqizo

Amakhodi Engozi	I-R11 – Ivutha Kakhulu R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R39/23/24/25 - R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe. R52 – Iyingozi ezintweni eziphila emanzini R36/38 – Ukucasuka emehlweni nasesikhumbeni.
Incazelo Yokuphepha	S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. I-S38 – Uma kungekho kungena komoya okwanele, gqoka izinto zokuphefumula ezifanele. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha. I-S28A - S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Isingeniso

Ikhwalithi:

1. I-Pyridine iwuketshezi olungenambala olunephunga elinamandla le-benzene.

2. Inephuzu eliphezulu lokubilisa kanye nokuguquguquka, futhi ingancibilika ezinhlobonhlobo zezincibilikisi eziphilayo, kodwa kunzima ukuncibilika emanzini.

3. I-Pyridine iyi-alkaline eyenza ama-acids angathathi hlangothi emanzini.

4. I-Pyridine ingaba ne-hydrogen bonding nezinhlanganisela eziningi.

Sebenzisa:

1. I-Pyridine ivame ukusetshenziswa njenge-solvent ekuphenduleni kwe-organic synthesis, futhi ine-solubility ephezulu yezinhlanganisela eziningi ze-organic.

2. I-Pyridine nayo inezinhlelo zokusebenza ekuhlanganiseni izibulala-zinambuzane, njengokuhlanganiswa kwezibulala-sikhunta nezibulala-zinambuzane.

Indlela:

1. I-Pyridine ingalungiswa ngohlu lwezindlela ezihlukene zokuhlanganisa, ezivame ukusetshenziswa kakhulu ezitholakala ngokunciphisa i-hydrogenation ye-pyridinexone.

2. Ezinye izindlela ezivamile zokulungiselela zihlanganisa ukusetshenziswa kwe-ammonia ne-aldehyde compounds, ukusabela okwengeziwe kwe-cyclohexene ne-nitrogen, njll.

Ulwazi Lokuphepha:

1. I-Pyridine iyi-solvent ephilayo futhi inokuguquguquka okuthile. Kumele kuqashelwe izimo zaselabhorethri ezinomoya omuhle uma usebenzisa ukugwema ukuhogela ngokweqile.

2. I-Pyridine iyacasula futhi ingase ibangele ukulimala kwamehlo, isikhumba, kanye nomgudu wokuphefumula. Imishini yokuzivikela efanele, okuhlanganisa amagilavu, izibuko, namamaski okuzivikela, kufanele kugqokwe ngesikhathi sokusebenza.

3. Izinyathelo ezifanele zokuvikela nokulawula ziyadingeka kubantu abaye babhekana ne-pyridine isikhathi eside.

Okwedlule: 2-Methyltetrahydrothiophen-3-One (CAS#13679-85-1)

Olandelayo: 2,5-Dihydroxy-1,4-dithiane(Mercaptoacet-aldehyde dimer) (CAS#40018-26-6)
