Intshayelelo

I-Butyl propionate (ekwaziwa njengepropyl butyrate) yikhompawundi ephilayo. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-butyl propionate:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala.

- Ukunyibilika: ukunyibilika kwiialkoholi kunye nezinyibilikisi ze-ether, ezinganyibiliki emanzini.

- Ivumba: Inevumba elifana nesiqhamo.

 

Sebenzisa:

- Usetyenziso lwemizi-mveliso: I-Butyl propionate sisinyibilikisi esibalulekileyo esisetyenziswa kakhulu kwimizi-mveliso efana neepeyinti, ii-coatings, ii-inki, izinto zokuncamathelisa, kunye nezicoci.

 

Indlela:

I-Butyl propionate idla ngokulungiswa yi-esterification, efuna ukuphendulwa kwe-propionic acid kunye ne-butanol, kunye ne-catalysts esetyenziswa ngokuqhelekileyo ibandakanya i-sulfuric acid, i-tolene sulfonic acid, okanye i-alkyd acid.

 

Ulwazi ngoKhuseleko:

- Umphunga we-butyl propionate unokubangela ukucaphuka kwamehlo kunye nokuphefumla, ke nikela ingqalelo ekungeneni komoya xa uyisebenzisa.

Kuphephe ukuvezwa ixesha elide kwi-butyl propionate, enokubangela ukucaphuka kunye nokoma xa udibana nolusu.

- Xa uphethe kwaye ugcina, landela iinkqubo zokuphatha ngokukhuselekileyo iikhemikhali ezifanelekileyo, sebenzisa izilumkiso ezifanelekileyo, kwaye uphephe ukudibana nemithombo yokutshisa.
