Hiki ke hoʻohana ʻia ka Tetraethylene glycol dimethyl ether ma ke ʻano he mea hoʻoheheʻe maikaʻi loa no nā hydrides gula alkaline;
Hoʻohana ʻia ka Tetraethylene glycol dimethyl ether i nā kaʻina hana kemika like ʻole e like me ka condensation alkylation a me ka hōʻemi;
Ma muli o kona kumu Lewis, hiki i ka Tetraethylene glycol dimethyl ether ke koho koho i nā kinoea ʻakika no ka hoʻomaʻemaʻe ʻana i ke kinoea synthesis, kinoea maoli, acetylene, a me nā kinoea ʻē aʻe; Māhele kūmau ke kinoea chromatography.
1. Tetraethylene glycol dimethyl ether (TEGDME) E hoʻohana i nā ipu i hana ʻia me nā mea kūpono i kūpono me TEGDME, e like me ke aniani a i ʻole kekahi mau plastic (e laʻa, polyethylene kiʻekiʻe). E hōʻoia i ka hoʻopaʻa paʻa ʻia o ka ipu i mea e pale aku ai i ka haumia a me ka evaporation.
2. Pono e ho'opa'a 'ia nā pahu a pau me ka inoa kemika, ka mana'o, ka 'ike pilikia, a me ka lā i loa'a mai ai. Kōkua kēia i ka ʻike ʻana i ka waiwai a hōʻoia i ka mālama pono ʻana.
3. E mālama iā TEGDME ma kahi maloʻo maloʻo ma kahi mamao loa mai ka lā a me ka wela. ʻO ka mea kūpono, pono e mālama ʻia ma ka lumi wela, akā e ʻoluʻolu e nānā i ka Pepa ʻIkepili Palekana (SDS) no nā ʻōlelo aʻoaʻo wela o ka mālama ʻana.
4. E ho'opa'a pono i ka ho'oku'u 'ia 'ana o nā wahi e mālama ai i mea e pale aku ai i ka ho'ouluulu 'ana o nā mahu.
5. E mālama iā TEGDME mai nā mea like ʻole e like me nā oxidants ikaika, nā ʻakika a me nā kumu no ka pale ʻana i nā hopena ʻino.
6. ʻAʻole hiki ke komo i nā wahi mālama i nā limahana i hoʻomaʻamaʻa wale ʻia a e hoʻopaʻa pono i nā lako palekana kūpono (e laʻa me nā mīkina lima, nā maka aniani) i hoʻopaʻa ʻia no ka mālama ʻana i nā kemika.
7. Tetraethylene glycol dimethyl ether (TEGDME) E hoʻohana i nā mea e hoʻomalu ai i ke kahe ʻana, e like me nā mea hoʻoheheʻe ʻia a i ʻole nā ʻeke ʻeke ʻeke, i ka wā o ke kahe ʻana a i ʻole ka hū.
8. E kamaʻāina i nā kaʻina hana ulia pōpilikia i ka wā i ʻike ʻia ai ʻole e kahe ʻana a e hōʻoia i ka loaʻa koke ʻana o nā pepa ʻikepili palekana.
