Izinga Likazwelonke le-Propionic Acid (Imininingwane ye-GB)
I-Propionic Acid National Standard (Izincazelo ze-GB) Izinga likazwelonke le-propionic acid lichaza ngokucacile ukubukeka kwayo: kufanele ibe uketshezi olungenambala, olusobala olunephunga elimnandi, futhi umbala wayo kumele uhlangabezane nezindinganiso ezithile zombala ezibonakalayo (isb., ngenani le-APHA elingadluli i-s...Funda kabanzi -
Izinyathelo Zokuqapha Nokugcina I-Propionic Acid.
Izinyathelo Zokuqapha Nokugcina I-Propionic Acid Gcina endaweni yokugcina izinto epholile, enomoya omuhle. Gcina i-Propionic Acid kude nemithombo yokushisa nokushisa. Izinga lokushisa lendawo yokugcina izinto akufanele lidlule ku-30°C. Gcina izitsha zivaliwe kahle. Gcina ngokwehlukana nama-oxidizing agents, ama-reducing agents, kanye...Funda kabanzi -
Ukupakishwa kwe-Propionic Acid.
Ukupakishwa kwe-Propionic Acid I-Propionic acid enokuhlanzeka okungu-99.5% noma ngaphezulu kumele ipakishwe ezitsheni ze-alloy noma ze-aluminium. I-propionic acid encibilikisiwe ayikwazi ukugcinwa emathangini e-aluminium; sebenzisa amathangi ensimbi ye-alloy noma ensimbi yekhabhoni ene-plastic lining esikhundleni salokho. Izinyathelo Zokuphepha Nokuphepha ze-Propionic Acid ...Funda kabanzi -
Ukusetshenziswa kwe-Propionic Acid.
Ukusetshenziswa kwe-Propionic Acid I-Propionic acid iyinto eluhlaza yokwenziwa kwezinto eziphilayo, esetshenziswa kakhulu ukukhiqiza ama-propionate nama-ester. Usawoti wayo we-calcium ne-sodium usebenza njengezithako zokugcina izinto ezinhle kakhulu zezimpahla ezibhakiwe kanye nokusanhlamvu. Ama-ester ayo asetshenziswa njengezithako ezikhethekile ezinukweni nasezimbozweni. I-Phenyl...Funda kabanzi -
Ifomula Yesakhiwo se-Propionic Acid
I-Propionic Acid (i-Propanoic Acid) Igama lesiNgisi: i-propionic acid; i-propanoic acid I-Propionic Acid Ifomula Yesakhiwo: CH₃CH₂COOH Ifomula Yamamolekyuli: C₃H₆O₂ Izakhiwo Zomzimba Nezamakhemikhali I-Propionic acid iwuketshezi olungenambala olunephunga elimnandi. Ubuningi obuhlobene: 0.992 I-Propionic Acid Iphuzu lokuncibilika: -22...Funda kabanzi -
Ukusetshenziswa kwe-Oxalic Acid.
Ukusetshenziswa kwe-Oxalic Acid I-Oxalic acid isetshenziswa kabanzi emikhakheni eyahlukene yezimboni: Imboni yezemithi: Isetshenziswa ekukhiqizeni imithi efana ne-chlortetracycline, i-oxytetracycline, i-tetracycline, i-streptomycin, i-vitamin B12, i-phenobarbital, i-calcium pantothenate, i-borneol, kanye ne-sodium iodoxam...Funda kabanzi -
Indlela Yokuxova I-Glyoxal ye-Oxalic Acid
Indlela Yokuxova I-Glyoxal ye-Oxalic Acid I-Glyoxal inokwehliswa okunamandla, ngakho-ke ingaxovaniswa ngokushesha ibe yi-oxalic acid ngaphansi kwesenzo se-nitric acid enamandla yokuxova. Ngenxa yezici ezifana nokutholakala kwezinto zokusetshenziswa, intengo, kanye nobuchwepheshe, le ndlela inokuncintisana okuncane emakethe futhi ayizange...Funda kabanzi -
Indlela Yokuxova I-Propylene Oxidation ye-Oxalic Acid
Indlela Yokuxova I-Propylene ye-Oxalic Acid Le nqubo yokuxova ihlukaniswe ngezinyathelo ezimbili: ukuxova i-propylene nge-nitric acid ukuyiguqula ibe yi-α-nitro lactic acid, bese kuba nokuxova i-catalytic ukuze kutholakale i-oxalic acid. Indlela yokuxova i-propylene ikhiqiza i-oxalic acid yezinga lezimboni...Funda kabanzi -
Indlela Yokufaka I-Oxalic Acid ku-Ethylene Glycol Nitric Acid
Indlela Yokuxutshwa Kwe-Ethylene Glycol Nitric Acid ye-Oxalic Acid Le nqubo yokuxutshwa kwe-oxidation ifana kakhulu nendlela yokuxutshwa kwesitashi. Isixazululo se-ethylene glycol esimanzi sishiswa ku-60 °C, bese kuthi i-acid exubile (30%–40% sulfuric acid ngobuningi, 20%–25% nitric acid ngobuningi) kanye ne-vanadium pentoxide kufakwe...Funda kabanzi -
Indlela ye-Sodium Formate ye-Oxalic Acid
Indlela ye-Sodium Formate ye-Oxalic Acid Ukukhiqizwa kwe-oxalic acid ngendlela ye-sodium formate kuhlukaniswe ngendlela ye-lead kanye nendlela ye-calcium. I-Carbon monoxide imuncwa yisisombululo se-sodium hydroxide ukuze kutholakale i-sodium formate, bese ikhishwa i-hydrogen ukuze kwakhiwe i-sodium oxalate. I-lat...Funda kabanzi -
Indlela Yokuhlanganisa I-Oxalic Acid Carbon Monoxide
Indlela Yokuhlanganisa I-Oxalic Acid Carbon Monoxide Le ndlela ekuqaleni yasebenzisa usawoti we-palladium nowethusi njengezinto ezibangela uketshezi, futhi yenza ukusabela kokuhlangana kwe-carbon monoxide, i-oxygen, i-alcohol, kanye ne-nitric acid encibilikisiwe ku-8–11 MPa kanye no-90–100 °C. Ukusabela kuqala kukhiqiza i-oxalate ester, ...Funda kabanzi -
Indlela Yokuxuba Ama-carbohydrate e-Oxalic Acid.
