1. ʻO Ethylene glycol monomethyl ether (pōkole ʻia ʻo MOE), i ʻike ʻia ʻo ethylene glycol monomethyl ether, he wai aniani ʻeleʻele ʻole, hiki ke hoʻopili ʻia me ka wai, ka waiʻona, ka acetic acid, acetone a me DMF.Ma ke ʻano he mea hoʻoheheʻe koʻikoʻi, hoʻohana nui ʻia ʻo MOE i nā ʻaila like ʻole, cellulose acetate, cellulose nitrate, nā waiʻona waiʻona a me nā resins synthetic.
2.Fast maloʻo'ūheheʻe no ka enamel a me ka varnish, uhi diluents, penetrant a me ka pae hoʻohālikelike i loko o ka dye 'oihana, ua hoʻohana 'ia no ka paʻi 'īnika, hoʻomākaukau sealants, a me ka hana plasticizers.I kēia mau makahiki i hala iho nei, ua hoʻohana nui ʻia ʻo MOE i ka ʻoihana lāʻau lapaʻau, aviation jet fuel anti icing agents, brake oil diluents, etc., a ua hoʻonui ʻia kona dosage i kēlā me kēia makahiki.Loaʻa ia ma ka hopena o ka ethylene oxide me ka methanol.
3.Colorless transparent wai me ka ʻala ʻoluʻolu.Hiki ke hui pū me ka wai, ethanol, ether, glycerol, acetone a me N, N-dimethylformamide.
4. Loaʻa iā ia ma ka hopena o ka ethylene oxide me ka methanol.E hoʻohui i ka methanol i ka boron trifluoride ether complex, e hoʻohui i ka ethylene oxide ma 25-30 ℃ ma lalo o ka hoʻoulu ʻana, a piʻi koke ka mahana i 38-45 ℃ ma hope o ka hala ʻana.E hoʻokaʻawale i ka hopena hoʻonā i loaʻa me ka pāhare hydrocayanide methanol solution i ph=8-9chemicalbook.Hoʻihoʻi hou i ka methanol, distill, a hōʻiliʻili i ka hakina ma mua o 130 ℃ no ka loaʻa ʻana o ka huahana pala.A laila e hoʻokaʻawale a hōʻiliʻili i ka hakina 123-125 ℃, ʻo ia ka huahana i pau.I ka hana ʻoihana, hoʻololi ʻia ka ethylene oxide a me ka methanol anhydrous i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, a hiki ke loaʻa nā huahana kiʻekiʻe me ka ʻole o nā catalysts.

1. Hoʻohana ʻia ʻo ia e like me ka solvent coating, penetrant, leveling agent a me ka synthesis organic intermediate, a me kahi mea hoʻohui no ka wahie jet.
ʻO 2.2-methoxyethanol, i kapa ʻia ʻo ethylene glycol monoether, ʻo ia ka mea waena o ka herbicide ethersulfonyl methyl, a me ka mea hoʻoheheʻe o ka nitrocellulose a me ka resin synthetic.
3. Hoʻohanaʻia kēia huahana ma keʻano he mea hoʻoheheʻe no nāʻaila likeʻole, lignin, nitrocellulose, cellulose acetate, nā waiʻona waiʻona a me nā resins synthetic;ʻO Chemicalbook, kahi reagent no ka hoʻoholo ʻana i ka hao, ka sulfate a me ka carbon disulfide, a me ka thinner no ka uhi ʻana, ua hoʻohana ʻia i ka hoʻopili a me ka sila ʻana o cellophane, ka varnish maloʻo wikiwiki a me ka enamel.Hiki ke hoʻohana ʻia ma ke ʻano he penetrant a leveling agent i ka ʻoihana dye, a i ʻole he plasticizer a me ka brightener.
4. Hoʻoholo i ka hao;Sulfate a me carbon disulfide reagents, hoʻohana ʻia e like me nā ʻaila like ʻole;Lignin;Nitrocellulose;Cellulose acetate;Nā mea hoʻoheheʻe no ka waiʻona hiki ke hoʻoheheʻe ʻia a me nā resins synthetic.
