Whakaahuatanga Hua:
Ko te Glycerin, e mohiotia ana ko te glycerol i roto i nga paerewa a-motu, he kore tae, he kakara, he reka.kakarate whakauru i te matū waro me te ahua o te wai kirikiri maramara.E mohiotia ana ko te glycerol.Ko te Glycerol, ka taea te tango i te makuku mai i te hau, engari ka uru ano hoki te hauwai sulfide, te hauwai hauwai me te whanariki hauota.
Ngā Āhuatanga Hua me te Pūmautanga:
1.Karekau he tae, he maamaa, he hongi, he wai kirikiri me te reka reka me te hygroscopicity.Ka uru ki te wai me te waipiro, amine, phenols ahakoa te rahinga, he koretake te wairewa wai.Wairewa i roto i te 11 wa ethyl acetate, tata ki te 500 wa ether.Kare e rewa ki te benzene, chloroform, waro tetrachloride, waro disulfide, petroleum ethers, hinu, waipiro ngako mekameka roa.Ka mura, ka whakaparahako me te pahūtanga ina tutaki ana ki nga apiha whakahaora kaha penei i te chromium dioxide me te konupora chlorate.He whakarewa pai hoki mo te maha o nga tote parakore me nga hau.Kore-waikura ki nga konganuku, ka taea te waikura ki te acrolein ina whakamahia hei whakarewa.
2.Ko nga ahuatanga matū: te tauhohenga esterification me te waikawa, penei me te benzene dicarboxylic acid esterification ki te whakaputa kapia alkyd.Tauhohenga whakawhiti me te hākawa.Ka tauhohe ki te hauwai pūhaumāota ki te hanga waipiro māota.E rua nga huarahi o te whakamaroketanga o te Glycerol: te whakamaroketanga i waenga ngota ki te tiki i te diglycerol me te polyglycerol;te whakamaroke i roto i te ngota ki te tiki acrolein.Ka tauhohe a Glycerol me nga turanga ki te hanga waipiro.Ko te tauhohenga ki te aldehydes me te ketones ka whakaputa acetals me te ketones.Ko te waikura me te waikawa nitric dilute ka puta te glyceraldehyde me te dihydroxyacetone;te hāora me te waikawa wā ka puta te waikawa formic me te formaldehyde.Ma te kaha o te waikura penei i te chromic anhydride, te pāhare pāporo pāhare pāporo, te pāhare pāporo permanganate rānei, ka taea te wera, te pahū ranei.Ka taea hoki e Glycerol te mahi i te nitrification me te acetylation.
3.Kore-paitini.Ahakoa te tapeke o te inu ki runga ki te 100g o te wairewa waimeha he kino, i roto i te tinana i muri i te hauwai me te hāoratanga ka waiho hei puna matūkai.I roto i nga whakamatautau kararehe, he rite tonu te awenga o te rewharewha ki te waipiro ina mahia kia inumia he nui rawa atu.
4. Kei roto i te tunu tupeka, te tupeka riu ma, te tupeka kakara, me te paowa hikareti.
5.Ka puta noa i roto i te tupeka, te pia, te waina, te koko.
Taupānga Hua:
1. Ahumahi Resin: whakamahia i roto i te hanga o te kapia alkyd me te kapia epoxy.
2. Ahumahi whakakikorua: whakamahia i roto i te ahumahi paninga ki te hanga momo alkyd resins, polyester resins, glycidyl ethers me epoxy resins, etc.
3. Ahumahi pueru me te ta me te tae tae: whakamahia hei whakahinuhinu, hei kai makuku, hei kaikawe mo te korukoru o te papanga, he kaihoko whakamaarama me te kaihoko uru.
Tikanga Rokiroki Hua:
1. Rokiroki i roto i te wahi ma, me te maroke, kia whakarongo ki te rokiroki hiri.Kia whai whakaaro ki te makuku-tohu, te wai-tohu, exothermic, tino aukati i te uru ki nga waiora kaha.Ka taea te penapena i roto i nga ipu tine-whakakikoruatia, i nga ipu kowiri tira ranei.
2. Kikī i roto i te pahū konumohe, pahū rino piauau ranei rongoa i roto i tāke kapihia ki te kapia phenolic.Me tiaki mai i te makuku, te wera me te wai i te wa e rokiroki ana me te kawe.Karekautia te whakauru i te glycerol ki te taha o nga mea whakahaora kaha (hei tauira, te waikawa nitric, te pāhare pāporo, me etahi atu).Me penapena me te kawe i runga i nga ture matū muramura.
Nga Tuhipoka Rokiroki Hua:
1. Rokiroki i roto i te whare putunga hauhautanga, whai hau.
2.Kia matara atu i te ahi me te puna wera.
3. Kia hiritia te ipu.
4.Me penapena motuhake mai i nga kaihoko oxidizing, whakaiti i nga kaihoko, alkalis me nga matū kai, kaua e uru ki te rokiroki.
5.Kua whakauruhia ki te momo tika me te nui o nga taputapu patu ahi.
6.Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere leakage me nga taonga whakaruru tika.
