Isingeniso

I-1,9-Nonanediol iyi-diol enama-athomu e-carbon ayisishiyagalolunye. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-1,9-nonanediol:

 

Ikhwalithi:

I-1,9-Nonanediol iqinile enamakristalu amhlophe endaweni yokushisa yegumbi. Inezici zokungabi nambala, ezingenaphunga, futhi zincibilike kuzincibilikisi zemvelo ezifana namanzi, i-ether, ne-acetone. Kuyinhlanganisela engaguquguquki futhi inobuthi obuphansi.

 

Sebenzisa:

I-1,9-Nonanediol inezinhlelo zokusebenza eziningi embonini yamakhemikhali. Ingasetshenziswa njenge-solvent kanye ne-solubilizer, futhi ingasetshenziswa kwezemithi, odayi, ama-resin, okokugqoka, amapulasitiki, nezinye izimboni. Inezici ezinhle zokukhiya futhi ingasetshenziswa futhi njenge-emulsifier, i-ejenti yokumanzisa kanye ne-stabilizer.

 

Indlela:

Kunezindlela eziningana zokulungisa i-1,9-nonanediol, futhi enye yezindlela ezivame ukusetshenziswa iwukuhlanganisa kusuka ekuphenduleni kwe-hydrogenation ye-nonanal. I-Nonanal ihlangana ne-hydrogen phambi kwe-catalyst ukukhiqiza i-1,9-nonanediol.

 

Ulwazi Lokuphepha:

I-1,9-Nonanediol inobuthi obuphansi futhi iphephile ukusetshenziswa ezimbonini. Njengento yamakhemikhali, lezi zinyathelo zokuphepha ezilandelayo kufanele ziqashelwe:

- Gwema ukuthinta isikhumba namehlo. Uma kwenzeka uthintana, hlambulula ngokushesha ngamanzi amaningi futhi uthintane nodokotela.

- Ngesikhathi sokusebenzisa, umoya omuhle kufanele usetshenziselwe ukugwema ukuhogela amagesi noma umhwamuko.

- Lapho ugcina futhi uphatha, kufanele ivikelwe ekuxhumaneni nama-oxidants kanye nezinto ezinamandla ze-oxidizing ukugwema umlilo noma ukuqhuma.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokuzivikela ngesikhathi sokusebenzisa.
