1,3-Dihydroxyacetone Introduction

ʻO 1,3-Dihydroxyacetone he mea hoʻohuihui me ka molecular formula C3H6O3, he polyhydroxyketose a me ka ketose maʻalahi.ʻO ka hiʻohiʻona he aniani pauka keʻokeʻo, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka wai, ethanol, ether, a me ka acetone.ʻO ka helu hoʻoheheʻe he 75-80 ℃, a ʻo ka solubility wai he> 250g / L (20 ℃).He ʻono kona a paʻa i ka pH 6.0.ʻO 1,3-Dihydroxyacetone kahi kōpaʻa hoʻohaʻahaʻa.ʻO nā monosaccharides a pau (inā loaʻa nā hui aldehyde manuahi a i ʻole ketone carbonyl) hiki ke hoʻemi.Hoʻokō ʻo Dihydroxyacetone i nā kūlana i luna, no laila pili ia i ka māhele o ka hoʻohaʻahaʻa i ke kō.

Aia nā ʻano hana synthesis kemika a me nā ʻano hana fermentation microbial.ʻEkolu mau hana kemika nui no ka 1,3-dihydroxyacetone: electrocatalysis, metal catalytic oxidation, a me formaldehyde condensation.ʻO ka hana kemika o 1,3-dihydroxyacetone aia nō i ka pae noiʻi noiʻi.ʻO ka hana ʻana o 1,3-dihydroxyacetone ma ke ʻano biological he mau pōmaikaʻi koʻikoʻi: kiʻekiʻe kiʻekiʻe o ka huahana, kiʻekiʻe glycerol huli hoʻololi a me nā kumu kūʻai haʻahaʻa.ʻO ka hana ʻana o 1,3-dihydroxyacetone ma Kina a me nā ʻāina ʻē e hoʻohana nui i ke ʻano o ka hoʻololi ʻana o ka microbial o glycerol.

ʻO ke ʻano hana hoʻohui kemika

1. Hoʻohui ʻia ka 1,3-dihydroxyacetone mai ka 1,3-dichloroacetone a me ka ethylene glycol ma ke ʻano he kumu kumu ma o ka pale carbonyl, etherification, hydrogenolysis, a me ka hydrolysis.Hoʻomaʻamaʻa ʻia ka 1,3-dichloroacetone a me ka ethylene glycol i loko o toluene e hana i ka 2,2-dichloromethyl-1,3-dioxolane.A laila hana lākou me ka sodium benzylidene i N, N-dimethylformamide e hana i 2,2-dibenzyloxy-1,3-dioxolane, a laila hydrogenated ma lalo o Pd/C catalysis e synthesize 1,3-dioxolane-2,2-dimethanol, ka mea. a laila hydrolyzed i loko o hydrochloric waika e hana 1,3-dihydroxyacetone.ʻO ka mea maka no ka synthesizing 1,3-dihydroxyacetone me ka hoʻohana ʻana i kēia ʻano maʻalahi ke loaʻa, ʻoluʻolu nā ʻano hopena, a hiki ke hana hou ʻia ka catalyst Pd / C, nona ka waiwai noi nui.

2. Ua hana ʻia ka 1,3-dihydroxyacetone mai ka 1,3-dichloroacetone a me ka methanol ma o ka pale carbonyl, etherification, hydrolysis, a me nā hopena hydrolysis.Hoʻopili ka 1,3-dichloroacetone me ka methanol anhydrous nui ma ke alo o kahi absorbent e hana i ka 2,2-dimethoxy-1,3-dichloropropane, a laila hoʻomehana ʻia me ka sodium benzylate i N, N-dimethylformamide e hana i 2,2-dimethoxy. -1,3-dibenzyloxypropane.A laila ua hydrogenated ma lalo o Pd / C catalysis e hana 2,2-dimethoxy-1,3-propanediol, a laila hydrolyzed i loko o hydrochloric waika e hana 1,3-dihydroxyacetone.Hoʻololi kēia ala i ka pale carbonyl mai ka ethylene glycol a i ka methanol, e maʻalahi ai ka hoʻokaʻawale a hoʻomaʻemaʻe i ka huahana 1,3-dihydroxyacetone, nona ka hoʻomohala koʻikoʻi a me ka waiwai noi.

3. Synthesis o 1,3-dihydroxyacetone me ka hoʻohana ʻana i ka acetone, methanol, chlorine a i ʻole bromine ma ke ʻano he kumu kumu.Hoʻohana ʻia ka Acetone, anhydrous methanol, a me ke kinoea chlorine a i ʻole bromine e hana i ka 2,2-dimethoxy-1,3-dichloropropane a i ʻole 1,3-dibromo-2,2-dimethoxypropane ma o ke kaʻina hana hoʻokahi.Hoʻopili ʻia lākou me ka sodium benzylate e hana i ka 2,2-dimethoxy-1,3-dibenzyloxypropane, a laila hydrogenated a hydrolyzed e hana i 1,3-dihydroxyacetone.ʻO kēia alahele he mau kūlana hoʻonā haʻahaʻa, a ʻo ka hopena "hoʻokahi ipu" e pale i ka hoʻohana ʻana i ka 1,3-dichloroacetone kumu kūʻai a me ka hoʻonāukiuki, e lilo ia i mea haʻahaʻa a waiwai nui no ka hoʻomohala ʻana.

Nā noi

ʻO 1,3-Dihydroxyacetone kahi ketose kūlohelohe i biodegradable, hiki ke ʻai, a ʻaʻohe mea ʻawaʻawa i ke kino kanaka a me ke kaiapuni.He mea hoʻohui multifunctional hiki ke hoʻohana ʻia i loko o nā mea hoʻonaninani, lāʻau lapaʻau, a me nā ʻoihana meaʻai.

Hoʻohana ʻia i ka ʻoihana cosmetic

Hoʻohana nui ʻia ʻo 1,3-Dihydroxyacetone ma ke ʻano he kumu hoʻohui i nā mea hoʻonaninani, ʻoi aku hoʻi me ka sunscreen me nā hopena kūikawā, hiki ke pale i ka nui o ka evaporation o ka ʻili o ka ʻili, a pāʻani i ka moisturizing, ka pale ʻana i ka lā, a me ka pale radiation UV.Eia kekahi, hiki i nā pūʻulu hana ketone i DHA ke hana me nā amino acids a me nā hui amino o ka keratin ʻili e hana i ka polymer brown, e hoʻoulu ai i ka ʻili o nā kānaka i kahi kala ʻeleʻele.No laila, hiki ke hoʻohana ʻia ma ke ʻano he simulant no ka ʻike ʻana i ka lā e loaʻa ai ka ʻili ʻeleʻele a ʻeleʻele paha e like me ka hopena o ka ʻike lōʻihi ʻana i ka lā, e nani ai.

E hoʻomaikaʻi i ka pakeneka ʻiʻo wīwī o nā puaʻa

ʻO 1,3-Dihydroxyacetone kahi huahana waena o ke kōpaʻa metabolism, e pāʻani ana i kahi hana koʻikoʻi i ke kaʻina hana o ke kō, e hōʻemi ana i ka momona o ke kino puaʻa a me ka hoʻomaikaʻi ʻana i ka pakeneka ʻiʻo lean.Ua hōʻike ka poʻe ʻepekema a me ka ʻenehana Iapana ma o nā hoʻokolohua e hoʻohui i kahi nui o DHA a me ka hui ʻana o ka pyruvate (paʻakai calcium) i ka hānai puaʻa (ma kahi ratio 3:1 kaumaha) hiki ke hoʻemi i ka momona o ka ʻiʻo puaʻa e 12% a 15%, a ʻo ka momona o ka ʻiʻo o ka wāwae a me ka ʻiʻo hope loa e hoʻemi ʻia, me ka hoʻonui ʻana i ka ʻike protein.

No nā meaʻai hana

ʻO ka hoʻohui ʻana i ka 1,3-dihydroxyacetone (ʻoi loa i ka hui pū ʻana me pyruvate) hiki ke hoʻomaikaʻi i ka metabolic rate o ke kino a me ka momona o ka waikawa momona, hiki ke puhi maikaʻi i ka momona e hōʻemi i ka momona o ke kino a hoʻopaneʻe i ka loaʻa ʻana o ke kaumaha (ka hopena kaumaha), a hoʻemi i ka nui o nā maʻi pili.Hiki iā ia ke hoʻomaikaʻi i ka naʻau o ka insulin a hoʻemi i ka pae cholesterol plasma i hoʻokumu ʻia e ka meaʻai cholesterol kiʻekiʻe.Hiki i ka supplementation lōʻihi ke hoʻonui i ka nui o ka hoʻohana ʻana i ke kō koko a mālama i ka glycogen muscle, No nā mea pāʻani, hiki iā ia ke hoʻomaikaʻi i kā lākou hana hoʻomanawanui aerobic.

Nā hoʻohana ʻē aʻe

Hiki ke hoʻohana pono ʻia ka 1,3-dihydroxyacetone ma ke ʻano he antiviral reagent.No ka laʻana, ma ka moʻomeheu embryo moa, hiki i ka hoʻohana ʻana i ka DHA ke pale nui i ka maʻi o ka maʻi distemper moa, e pepehi ana i ka 51% a 100% o ka maʻi.I ka ʻoihana ʻili, hiki ke hoʻohana ʻia ka DHA ma ke ʻano he mea pale no nā huahana ʻili.Eia kekahi, hiki ke hoʻohana ʻia nā preservatives i haku ʻia me DHA no ka mālama ʻana a me ka mālama ʻana i nā huaʻai a me nā mea kanu, nā huahana wai, a me nā huahana ʻiʻo.
