Intshayelelo

I-Ethyl (R) - (-) -3-hydroxybutyrate, eyaziwa nangokuthi (R) - (-) -3-hydroxybutyric acid ethyl ester, i-organic compound. Iimpawu zayo zezi zilandelayo:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala

 

Sebenzisa:

I-Ethyl (R)-(-)-3-hydroxybutyrate inoluhlu olubanzi lwezicelo kwinkalo yekhemistri:

- Inokudlala indima ebalulekileyo njenge-catalyst kwi-organic synthesis reactions.

 

Indlela:

Kukho iindlela ezininzi zokulungisa i-ethyl (R)-(-)-3-hydroxybutyrate:

- Indlela eqhelekileyo kukulungiselela nge-esterification ye-hydroxybutyric acid, ephendula i-hydroxybutyric acid kunye ne-ethanol, yongeza i-acid catalyst efana ne-sulfuric acid okanye i-asidi ye-formic, kwaye i-distills imveliso ecocekileyo emva kokusabela.

- Inokuthi ilungiswe ngokunciphisa i-asidi ye-succinic kunye ne-ethanol, ukongeza i-acid catalysts, kunye ne-hydrolysis.

 

Ulwazi ngoKhuseleko:

I-Ethyl (R)-(-)-3-hydroxybutyrate ikhuselekile xa isetyenziswa ngokubanzi, kodwa oku kulandelayo kusafuneka kuqatshelwe:

- Lulwelo olunokutsha kwaye kufuneka lugwenywe ekudibaneni nomlilo ovulekileyo kunye namaqondo okushisa aphezulu.

- Izilumkiso eziyimfuneko zokhuseleko, ezifana nokunxiba iiglasi zokukhusela kunye neeglavu, kufuneka zithathwe ngexesha lokusebenza.

- Kuphephe ukuphefumla, ukungeniswa, kunye nokunxibelelana kwesikhumba ukunqanda ukungonwabi kunye nokwenzakala.

- Kwimeko yoqhagamshelwano, hlambulula indawo echaphazelekayo ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.
