Isingeniso

I-1-nitropropane (eyaziwa nangokuthi i-2-nitropropane noma i-propylnitroether) iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esifushane kwezinye zezakhiwo zenkomponi, ukusetshenziswa, izindlela zokulungiselela, kanye nolwazi lokuphepha.

 

Ikhwalithi:

- I-1-Nitropropane iwuketshezi olungenambala oluvutha kancane endaweni yokushisa.

- Inhlanganisela inephunga elimnandi.

 

Sebenzisa:

- I-1-nitropropane isetshenziswa ngokuyinhloko njengento ebalulekile ephakathi ku-organic synthesis, engasetshenziselwa ukuhlanganiswa kwe-alkyl nitroketone, i-nitrogen heterocyclic compounds, njll.

- Ingasetshenziswa futhi njengengxenye yeziqhumane nama-propellants, asetshenziswa ezimbonini lapho kulungiswa iziqhumane ezine-nitro.

 

Indlela:

- I-1-Nitropropane ingalungiswa ngokusabela kwe-propane ne-nitric acid. Ukusabela ngokuvamile kwenziwa ngaphansi kwezimo ezine-asidi, futhi i-nitric acid ingasabela nge-propionic acid ukuze ithole i-propyl nitrate, engasabela ngokuqhubekayo nge-propyl alcohol propionate ukuze yakhe i-1-nitropropane.

 

Ulwazi Lokuphepha:

- I-1-Nitropropane iyisithako esinobuthi esicasulayo futhi esibolayo. Ukuchayeka noma ukuhogela umhwamuko wawo kungase kubangele ukucasuka kwamehlo, isikhumba, kanye nomgudu wokuphefumula.

- Ikhompiyutha kufanele isingathwe endaweni enomoya omuhle enezinyathelo zokuzivikela ezidingekayo, njengokugqoka izingubo zamehlo ezivikelayo, amagilavu, nezinsimbi zokuphefumula.

- 1-Nitropropane kufanele igcinwe endaweni epholile, eyomile, kude nomlilo nezinto ezivuthayo.

- Imithetho efanele yokuphepha yaselabhorethri kufanele ilandelwe lapho kusingathwa inhlanganisela.
