Fa'aoga

Fa'aaogaina i le fa'aogaina o meaola ma se mea mata e fai ai mea manogi

Fa'aoga

GB 2760-96 o loʻo faʻamaonia ai mea manogi e mafai ona faʻaaogaina. E masani ona faʻaaogaina e saunia ai faʻi, caramel ma isi fualaau suamalie.

Fa'aoga

butyraldehyde ose vaega taua tele. e mafai ona gaosia le n-butanol e ala i le hydrogenation o le n-butanal; 2-ethylhexanol e mafai ona gaosia e le condensation dehydration ona hydrogenation, ma le n-butanol ma 2-ethylhexanol o mea autu autu o plasticizers. n-butyric acid e mafai ona gaosia e ala i le faʻamaʻiina o le n-butyric acid; trimethylolpropane e mafai ona gaosia e ala i le condensation ma formaldehyde, o se plasticizer mo le tuufaatasia o resini alkyd ma se mea mata mo le suauu faamago ea; condensation i le phenol e maua ai resini solu suauu; condensation ma le urea e mafai ona maua ai le resin soluble ava malosi; oloa condensed i le polyvinyl alcohol, butylamine, thiourea, diphenylguanidine poʻo methyl carbamate o mea mataʻutia ma, condensation ma ava eseese o loʻo faʻaaogaina e avea o se solvent mo celluloid, resin, paʻu ma vailaʻau oloa; o loʻo faʻaaogaina le fale gaosi oloa e fai ai le "Mianerton", "pyrimethamine", ma le amylamide.

Fa'aoga

Kelu pa'u, pa'u accelerator, synthetic resin ester, gaosi butyric acid, ma isi. O lona vaifofo hexane o se reagent mo le fuafuaina o le osone. Faʻaaogaina e avea o se solvent mo lipids, faʻaaogaina foi i le sauniuniga o mea manogi ma mea manogi ma o se faʻasao.

Auala gaosiga

i le taimi nei, o le gaosiga o metotia o le butyraldehyde faaaoga auala nei: 1. propylene carbonyl synthesis auala propylene ma synthesis kasa faia carbonyl synthesis tali i le i ai o Co po Rh catalyst e maua ai le n-butyraldehyde ma isobutyraldehyde. Ona o le eseese catalysts ma tulaga faagasologa o loo faaaogaina, e mafai ona vaevaeina i le maualuga-omiga carbonyl synthesis ma cobalt carbonyl e fai ma catalyst ma maualalo-oomi carbonyl synthesis ma rhodium carbonyl phosphine complex e fai ma catalyst. O le auala maualuga o loʻo i ai le maualuga o le tali atu ma le tele o mea faʻatau, ma faʻateleina ai le tau o le gaosiga. O le maualalo o le mamafa o le carbonyl synthesis metotia e maualalo le faʻaogaina o le mamafa, fua o le isomer lelei o le 8-10: 1, faʻaitiitia mea faʻatau, maualuga le suiga o le suiga, maualalo mea mataʻutia, maualalo le faʻaaogaina o le eletise, meafaigaluega faigofie, faʻagasologa puupuu, faʻaalia aafiaga lelei tau tamaoaiga ma vave atinae. 2. Acetaldehyde condensation auala. 3. Butanol oxidative dehydrogenation metotia faʻaaogaina siliva e pei o se faʻamalosi, ma faʻamaʻi le butanol e le ea i le laasaga e tasi, ona faʻafefeteina ai lea o mea faʻafefe, vavae ese, ma faʻasaʻo ina ia maua ai le oloa maeʻa.

Auala gaosiga

E maua mai ile fa'amamago fa'amamago ole calcium butyrate ma le calcium formate.

O le ausa e maua i le dehydrogenation o le catalyst.
