  • Ethyl Ethanol

    ʻO Ethyl Ethanol

    ʻO Ethanol, i ʻike ʻia e ka mole mole C2H5OH a i ʻole EtOH, kahi wai kala ʻole, aniani ʻole, lapalapa a maʻalahi ʻole. ʻO Ethanol nona ka hapa nui ma mua o 99.5% i kapa ʻia he ethanol anhydrous. ʻike ʻia he wai ʻona, he wai kuni ʻole ia, maʻalahi ʻole i ke anuanu o ka lumi, kaomi o ka lewa, he ʻala kūikawā, ʻoluʻolu, a hoʻonāukiuki iki ka wai wai. ʻOi aku ka liʻiliʻi o ka Ethanol ma mua o ka wai a hiki ke hoʻonā ʻia i kēlā me kēia manawa Hiki ke hoʻoheheʻe ʻia i ka wai, methanol, ether a me chloroform. Hiki iā ia ke hoʻopau i nā hui kūlohelohe a me kekahi o nā mea hoʻohui ʻokanika.

  • Ethyl Acetate(≥99.7%)

    ʻO Ethyl Acetate (≥99.7%)

    ʻO Ethyl acetate kahi wai aniani moakaka ʻole me ka ʻaʻala o ka hua a maʻalahi. Hoʻololi -83 ℃, wahi paila 77 ℃, index index 1.3719, point flash 7.2 ℃ (cup open), hiki ke kuni ʻia me ka chloroform, ethanol, acetone a me ʻ ether, hiki ke hoʻoheheʻe ʻia i ka wai, akā me kekahi mau mea hoʻoheheʻe e hana i ka hui ʻana o ka azeotrope.

  • 1,6-Hexanediol

    1,6-Hexanediol

    ʻO 1, 6-hexadiol, a i ʻike ʻia hoʻi me 1, 6-dihydroxymethane, a i ʻole HDO no ka pōkole, aia kahi mole mole o C6H14O2 a me ka mole mole o 118.17. I ka mahana o ka lumi, he waxy keʻokeʻo keʻokeʻo ia, hiki ke hoʻoheheʻe ʻia i ka ethanol, ethyl acetate a me ka wai, a haʻahaʻa haʻahaʻa.
