Hoʻolauna
He wai waihoʻoluʻu ʻole, ʻala ʻole, ʻākala, hygroscopic viscous wai. He ʻono ʻono kona. Ua like kona hoʻoheheʻe ʻia me ka ethylene glycol, akā ʻoi aku ka ikaika o kona solubility i nā hydrocarbons. Diethylene glycol hiki ke miscible me ka wai, ethanol, ethylene glycol, acetone, chloroform, furfural, etc. He immiscible me etera, kalapona tetrachloride, kalapona disulfide, kaulahao pololei aliphatic hydrocarbon, aromatic hydrocarbon, etc. Rosin, shellac, cellulose acetate, a ʻo ka hapa nui o nā aila ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka diethylene glycol, akā hiki ke hoʻoheheʻe i ka cellulose nitrate, alkyd resins, polyester resins, polyurethane, a me ka hapa nui o nā mea pena. Hiki ke ahi, haʻahaʻa ka ʻona. Loaʻa nā waiwai kemika maʻamau o ka waiʻona a me ka etera.
Keʻano mālama
1. E mālama ma kahi maloʻo a maloʻo. E hōʻoia i ka ea maikaʻi ma ka hale hana.
2. E mālama i ke ahi a me ka wai. E mālama ʻia mai nā oxidants
Hoʻohana
1. Hoʻohana nui ʻia e like me ke kinoea dehydrating agent a me nā mea ʻala ʻala. Hoʻohana ʻia ʻo ia e like me ka solvent no cellulose nitrate, resin, grease, paʻi ʻīnika, textile softener, hoʻopau ʻana, a me ka unuhi ʻana o ka coumarone a me ka indene mai ka pā lanahu. Eia kekahi, hoʻohana pū ʻia ka diethylene glycol ma ke ʻano he paʻakikī ʻaila brake, celluloid softener, antifreeze a me ka diluent i ka emulsion polymerization. Hoʻohana pū ʻia no ka plasticizer rubber a me resin; Polyester resin; ʻO ke aniani aniani; ʻO ka pahu karbamate; ʻO ka hana ʻana o ka ʻaila hinu viscosity improver a me nā huahana ʻē aʻe. Hoʻohana ʻia no ka synthetic unsaturated polyester resin, etc.
2. Hoʻohana ʻia e like me ka synthetic unsaturated polyester resin, plasticizer, etc. Hoʻohana pū ʻia no ka antifreeze, ke kinoea dehydrating agent, plasticizer, solvent, aromatics extraction agent, cigarette hygroscopic agent, textile lubricant and finishing agent, paste a me nā ʻano mea like ʻole adhesive anti-drying agent. , VAT dye hygroscopic solvent, etc. He mea hoʻoheheʻe maʻamau ia no ka momona, resin a me ka nitrocellulose.
