Ulwazi lweReference

iimpahla i-lauraldehyde, ekwaziwa ngokuba yi-doylaldehyde, ayinambala kwaye ayibonakalisi ulwelo olunamafutha okanye iikristale ezifana negqabi, ezithi zifakwe i-oxid ukwenza i-lauric acid. Indalo ikhona kwii-oyile ezibalulekileyo ezifana neoli yelamuni, ioli yekalika kunye neoyile yerue.
isicelo Ilauraldehyde inencasa yealdehyde kunye negrisi. Ngamavumba amnandi entyatyambo kunye nesitrasi. Ingasetyenziswa ngamanani amancinci kwiintyatyambo zemihla ngemihla ezifana ne-lily yentlambo, intyatyambo ye-orange, i-violet, njl.
uhlalutyo lomxholo igqitywe yindlela yekholamu engekho-polar kwi-chromatography yegesi (GT-10-4).
ubuthi I-ADI 1 mg/kg((3E)). LD50 23000 mg / kg (impuku, ngomlomo).
umda wokusetyenziswa I-FEMA(mg/kg): isiselo esithambileyo 0.93; Isiselo esibandayo 1.5; Iilekese 2.4; Ukutya okubhakiweyo 2.8; I-Pudding 0.10; Gum candy 0.20 ~ 110. Umda ophakathi (i-FDA 172.515,2000).
sebenzisa I-GB 2760-1996 imisela ukuba kuvunyelwe okwethutyana ukusebenzisa iziqholo ezityiwayo. Ikakhulu isetyenziselwa ukulungiselela i-cream, i-caramel, ubusi, iibhanana, iilamuni kunye nezinye ii-citrus kunye neencasa ezixubeneyo zeziqhamo.
I-Dylaldehyde yindawo ephakathi kunye nesiqholo kwi-organic synthesis. Xa ihlanjululwe, inephunga elinamandla kunye nexesha elide elifana ne-violet, elingasetyenziselwa i-jasmine, i-moonshine, i-lily yentlambo kunye ne-violet flavour.
Indlela yokuvelisa Ilungiselelwe yi-oxidation ye-decanediol kunye nokunciphisa i-dodecanoic acid. Ukunciphisa i-dodecyl acid kwi-dodecyl aldehyde kuqhutyelwa kwi-250-330 ° C phambi kwe-formic acid kunye ne-methanol. Imveliso yokunciphisa ihlukaniswe kumanzi e-asidi, ihlanjwe ngamanzi, kwaye i-dodecylaldehyde ihlukaniswe ngokunciphisa uxinzelelo lwe-distillation. Ukusabela kokunciphisa kufuna i-titanium dioxide okanye i-manganese carbonate njenge-catalyst. I-Manganese carbonate ifunyenwe ngokusabela kwe-asidi ye-sulfuric kunye ne-sodium carbonate.
I-oxidized yi-lauryl alcohol. Okanye i-lauric acid iyancipha.
