1,3-Dihydroxyacetone Whakataki

Ko te 1,3-Dihydroxyacetone he pūhui pararopi me te tātai rāpoi C3H6O3, he polyhydroxyketose me te ketose māmā.Ko te ahua he karaihe paura ma, he ngawari te whakarewa i roto i nga whakarewa pararopi penei i te wai, te waihano, te etera, me te acetone.Ko te ira whakarewa he 75-80 ℃, me te wairewa he> 250g/L (20 ℃).He reka reka, he pumau ki te pH 6.0.Ko te 1,3-Dihydroxyacetone he huka whakaheke.Ko nga monosaccharides katoa (i te mea he aldehyde kore utu, he roopu waro ketone ranei) ka taea te whakaheke.Ka tutuki te Dihydroxyacetone ki nga tikanga o runga ake nei, na reira no te waahanga o te whakaheke huka.

He tikanga whakahiato matū me nga tikanga FERMENTATION microbial.E toru nga tikanga matū matua mo te 1,3-dihydroxyacetone: electrocatalysis, whakarewa catalytic oxidation, me te formaldehyde condensation.Ko te hanga matū o te 1,3-dihydroxyacetone kei roto tonu i te waahanga rangahau taiwhanga.Ko te hanga o te 1,3-dihydroxyacetone na roto i te tikanga koiora he nui nga painga: te nui o te kukū o te hua, te nui o te huringa glycerol me te utu iti.Ko te hanga o te 1,3-dihydroxyacetone i Haina me nga whenua o waho te nuinga o te whakamahi i te tikanga o te huringa microbial o te glycerol.

Tikanga whakahiato matū

1. Ko te 1,3-dihydroxyacetone te whakahiato mai i te 1,3-dichloroacetone me te ethylene glycol hei rauemi mata matua na roto i te whakamarumaru waro, te etherification, te hydrogenolysis, me te hydrolysis.Ko te 1,3-dichloroacetone me te ethylene glycol ka whakamahana me te refluxed i roto i te toluene hei whakaputa i te 2,2-dichloromethyl-1,3-dioxolane.Ka tauhohe ratou ki te konutai benzylidene i roto i te N, N-dimethylformamide ki te whakaputa i te 2,2-dibenzyloxy-1,3-dioxolane, katahi ka hauwai i raro i te Pd/C catalysis ki te whakahiato i te 1,3-dioxolane-2,2-dimethanol, e ka whakamarohia ki te waikawa maaota hei whakaputa i te 1,3-dihydroxyacetone.Ko nga rauemi mata mo te whakahiato i te 1,3-dihydroxyacetone ma te whakamahi i tenei tikanga he ngawari ki te whiwhi, he ngawari nga tikanga tauhohenga, a ka taea te recycled te Pd / C catalyst, he nui te uara tono.

2. I whakahiatotia te 1,3-dihydroxyacetone mai i te 1,3-dichloroacetone me te methanol na roto i te whakamarumaru waro, te etherification, te hydrolysis, me nga tauhohenga wai.1,3-dichloroacetone tauhohe ki te taikaha anhydrous mewaro i roto i te aroaro o te absorbent ki te whakaputa 2,2-dimethoxy-1,3-dichloropropane, e ka whakamahana ki te konutai benzylate i roto i te N, N-dimethylformamide ki te whakaputa 2,2-dimethoxy -1,3-dibenzyloxypropane.Katahi ka hauwaitia i raro i te Pd/C catalysis hei whakaputa i te 2,2-dimethoxy-1,3-propanediol, ka whakamaaramahia ki te waikawa puota hei whakaputa i te 1,3-dihydroxyacetone.Ka whakakapihia e tenei ara te kaiwawao waro mai i te ethylene glycol ki te methanol, he maamaa ake te wehe me te pure i te hua 1,3-dihydroxyacetone, he mea nui te whanaketanga me te uara tono.

3. Te whakahiato o te 1,3-dihydroxyacetone ma te whakamahi i te acetone, te methanol, te chlorine, te bromine ranei hei rauemi mata matua.Ka whakamahia te acetone, te methanol anhydrous, me te hau maota, te bromine ranei hei whakaputa i te 2,2-dimethoxy-1,3-dichloropropane, 1,3-dibromo-2,2-dimethoxypropane ranei na roto i te tukanga kohua kotahi.I muri iho, ka whakahiatotia ki te konutai benzylate hei whakaputa i te 2,2-dimethoxy-1,3-dibenzyloxypropane, katahi ka hauwaitia, ka whakamarohia hei whakaputa i te 1,3-dihydroxyacetone.He ngawari nga tikanga tauhohenga o tenei huarahi, a ko te "kotahi kohua" ka karo i te whakamahi i te 1,3-dichloroacetone utu nui me te riri, ka iti te utu me te tino utu mo te whanaketanga.

Nga tono

Ko te 1,3-Dihydroxyacetone he ketose karekau, ka taea te kai, kaore he paitini ki te tinana o te tangata me te taiao.He taapiri maha ka taea te whakamahi i roto i nga mahi whakapaipai, rongoa, me nga umanga kai.

Ka whakamahia i roto i te ahumahi whakapaipai

Ko te 1,3-Dihydroxyacetone te nuinga e whakamahia ana hei whakauru tauira i roto i nga mea whakapaipai, ina koa he whakamarumaru ra me nga paanga motuhake, ka taea te aukati i te nui o te makuku o te kiri, me te whai waahi ki te whakamakuku, te whakamarumaru o te ra, me te whakamarumaru i te rauropi UV.I tua atu, ka taea e nga roopu mahi ketone i roto i te DHA te urupare ki nga waikawa amino me nga roopu amino o te keratin kiri ki te hanga i te waerau parauri, ka puta te kiri o te tangata i te tae parauri horihori.Na reira, ka taea hoki te whakamahi hei tiunu mo te ra kia puta he kiri parauri, he kiri parauri ranei he rite te ahua ki te hua o te roanga o te ra ki te ra, kia ataahua ai.

Whakapai ake i te ōrau mīti hiroki o te poaka
