Ubungozi Nokuphepha

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
R38 – Ukucasuka esikhunjeni
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha.

Ulwazi Lwereferensi

izindlu I-lauraldehyde, eyaziwa nangokuthi i-doylaldehyde, iwuketshezi olunamafutha angenambala futhi olusobala noma amakristalu anjengeqabunga, afakwa oxid ukuze akhe i-lauric acid. Imvelo ikhona emafutheni abalulekile njengamafutha kalamula, amafutha omcako kanye namafutha e-rue.
isicelo I-lauraldehyde inokunambitheka kwe-aldehyde namafutha. Ngamakha amnandi ezimbali nesawolintshi. Ingasetshenziswa ngamanani amancane ku-flavour yansuku zonke yezimbali ezifana nomnduze wesigodi, i-orange blossom, i-violet, njll. Phakathi kwama-flavour adliwayo, ubhanana, i-citrus, izithelo ezixutshwe nezinye izithelo zokunambitheka zingalungiswa.
ukuhlaziya okuqukethwe kunqunywa indlela yekholomu engeyona ye-polar ku-chromatography yegesi (GT-10-4).
ubuthi I-ADI 1 mg/kg((3E)). LD50 23000 mg/kg (igundane, ngomlomo).
umkhawulo wokusetshenziswa I-FEMA(mg/kg): isiphuzo esibandayo 0,93; Isiphuzo esibandayo 1.5; Uswidi 2.4; Ukudla okubhakiwe 2.8; I-Pudding 0.10; I-Gum candy 0.20~110. Umkhawulo omaphakathi (FDA 172.515,2000).
sebenzisa I-GB 2760-1996 ibeka ukuthi kuvunyelwe okwesikhashana ukusebenzisa izinongo ezidliwayo. Ikakhulukazi esetshenziselwa ukulungisa ukhilimu, i-caramel, uju, ubhanana, ulamula kanye nezinye izithelo ezisawolintshi nezinambitheka ezixubile.
I-Dylaldehyde iyisinongo esiphakathi nendawo kanye ne-organic synthesis. Uma ihlanjululwe, inephunga eliqinile nelihlala isikhathi eside njenge-violet, elingasetshenziswa ku-jasmine, ukukhanya kwenyanga, umnduze wesigodi kanye nama-flavour violet.
Indlela yokukhiqiza Ilungiswa nge-oxidation ye-decanediol kanye nokunciphisa i-dodecanoic acid. Ukwehliswa kwe-dodecyl acid ku-dodecyl aldehyde kwenziwa ku-250-330 ° C lapho kukhona i-formic acid ne-methanol. Umkhiqizo wokunciphisa uhlukaniswa namanzi ane-asidi, ugezwe ngamanzi, futhi i-dodecylaldehyde ihlukaniswa ngokuncishiswa kwe-pressure distillation. Ukusabela kokunciphisa kudinga i-titanium dioxide noma i-manganese carbonate njenge-catalyst. I-Manganese carbonate itholakala ngokusabela kwe-sulfuric acid ne-sodium carbonate.
I-oxidized yi-lauryl alcohol. Noma i-lauric acid iyancipha.
