Oxidation e hana i ka glycerol aldehyde a me ka glycerol acid.Hoʻopaʻa ma 0°C, hana i nā kristal rhombohedral me ka ʻālohilohi.Hana ʻia ka polymerization ma kahi mahana o 150 ° C.ʻAʻole hiki ke hui pū ʻia me ka anhydride acetic anhydrous, potassium permanganate, nā waikawa ikaika, corrosives, fatty amines, isocyanates, oxidizing agents. |
Hōʻike huahana:
ʻO Glycerin, i kapa ʻia ʻo glycerol ma nā kūlana aupuni, he kala ʻole, ʻala ʻole, ʻono-pilauka mea olaola me ke ʻano o kahi wai ʻalohilohi.ʻIke mau ʻia ʻo glycerol.ʻO Glycerol, hiki ke hoʻopaʻa i ka makū mai ka lewa, akā e komo pū i ka hydrogen sulfide, hydrogen cyanide a me ka sulfur dioxide.
Nā Waiwai a me ka Paʻa:
1.Colorless, transparent, odourless, viscous wai me ka ono a me ka hygroscopicity.Hiki ke hui pū me ka wai a me nā waiʻona, nā amine, nā phenols i kēlā me kēia ʻāpana, ʻaʻohe ʻano wai wai.Hiki ke hoʻoheheʻe ʻia i 11 mau manawa ethyl acetate, ma kahi o 500 mau manawa eter.ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ethers, aila, nā ʻaila momona momona.Hiki ke puhi ʻia, hiki ke hoʻopau i ka puhi ʻana a me ka pahū ʻana i ka wā e hālāwai ai me nā mea hoʻoheheʻe ikaika e like me ka chromium dioxide a me ka potassium chlorate.He mea hoʻoheheʻe maikaʻi ia no nā paʻakai a me nā kinoea inorganic.Non-corrosive i nā metala, hiki ke oxidized i acrolein ke hoʻohana ʻia e like me ka solvent.
2. Kemimi waiwai: esterification pane me kaʻakika, e like me benzene dicarboxylic acid esterification e hana alkyd resin.ʻO ka hopena transesterification me ka ester.Hoʻopili me ka hydrogen chloride e hana i nā ʻawaʻawa chlorinated.ʻElua ala o ka hoʻoheheʻe ʻana o Glycerol: intermolecular dehydration e loaʻa ai ka diglycerol a me ka polyglycerol;ka wai maloʻo intramolecular e loaʻa ai ka acrolein.Hoʻopili ʻo Glycerol me nā kumu e hana i nā mea inu ʻona.ʻO ka hopena me nā aldehydes a me nā ketones e hoʻopuka i nā acetals a me nā ketones.ʻO ka oxidation me ka dilute nitric acid e hana i ka glyceraldehyde a me ka dihydroxyacetone;ʻO ka hoʻoheheʻe ʻana me ka waika manawa e hoʻopuka ai i ka waikawa formic a me ka formaldehyde.Me nā oxidants ikaika e like me chromic anhydride, potassium chlorate a i ʻole potassium permanganate contact, hiki ke hoʻoulu a pahū paha.Hiki i ka Glycerol ke pāʻani i ka hana o ka nitrification a me ka acetylation.
3.Non-toxic.ʻOiai inā ʻaʻole ʻino ka nui o ka inu ʻana a hiki i ka 100g o ka hopena dilute, i ke kino ma hope o ka hydrolysis a me ka oxidation a lilo i kumu o nā meaʻai.I loko o nā hoʻokolohua holoholona, ua like ka hopena anesthesia e like me ka waiʻona i ka wā e inu ʻia ai ka nui loa.
4. Loaʻa i ka baka baka, ka paka keʻokeʻo, ka paka ʻala, a me ka uahi paka.
5.Occurs maoli i ka paka, ka pia, ka waina, ka koko.
Hoʻohana huahana:
1. ʻOihana Resin: hoʻohana ʻia i ka hana ʻana i ka resin alkyd a me ka resin epoxy.
2. ʻO kaʻoihana hoʻopili: hoʻohanaʻia i kaʻoihana pale e hana i nāʻano alkyd resins, polyester resins, glycidyl ethers a me ka epoxy resins, etc.
3. ʻOihana lole a me ka paʻi ʻana a me ka waihoʻoluʻu: hoʻohana ʻia e hana i ka lubricant, moisture absorber, fabric wrinkle-proof shrinkage treatment agent, diffusion agent a me penetrating agent.
Nā ʻano hana mālama huahana:
1. E kūʻai ma kahi maʻemaʻe a maloʻo, pono e hoʻolohe i ka mālama ʻana i hoʻopaʻa ʻia.E hoʻolohe i ka moisture-proof, water-proof, exothermic, pāpā loa i ka hui ʻana me nā oxidants ikaika.Hiki ke mālama ʻia i loko o nā ipu i hoʻopaʻa ʻia a i ʻole nā pahu kila.
2. Hoʻopili ʻia i loko o nā pahu alumini a i ʻole nā pahu hao galvanized a i mālama ʻia i loko o nā pahu i hoʻopaʻa ʻia me ka resin phenolic.Pono e pale ʻia mai ka makū, ka wela a me ka wai i ka wā o ka mālama ʻana a me ka lawe ʻana.ʻAʻole ʻae ʻia ka hoʻohui ʻana i ka glycerol me nā mea oxidizing ikaika (e laʻa me ka waikawa nitric, potassium permanganate, etc.).Pono e mālama a lawe ʻia e like me nā lula kemika maʻamau.
Nā memo mālama huahana:
1. E kūʻai i loko o kahi hale kūʻai ʻoluʻolu.
2.E mālama i ke ahi a me ke kumu wela.
3. E hoʻopaʻa i ka pahu.
4. Pono e hoʻokaʻawale ʻia mai nā mea oxidizing, nā mea hoʻohaʻahaʻa, alkalis a me nā kinikona e hiki ke ʻai, mai hoʻohui i ka waiho ʻana.
5. Hoʻopiliʻia me nāʻano kūpono a me ka nui o nā mea hana ahi.
6. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia a me nā lako hale kūpono.
