ʻO ka Thymolphthalein CAS 125-20-2
ʻO ka inoa ʻepekema o Thymolphthalein ʻo "3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide", he mea hoʻohuihui organik. ʻO ke ʻano kemika ʻo C28H30O4, a ʻo ke kaumaha molekala he 430.54. He pauka kristal keʻokeʻo ia. He maʻalahi ke hoʻoheheʻe ʻia i loko o ka ether, acetone, sulfuric acid a me nā hopena alkaline, a ʻaʻole hoʻoheheʻe ʻia i ka wai. Hoʻohana pinepine ʻia ia ma ke ʻano he hōʻailona acid-base, a ʻo kona pae hoʻololi kala pH he 9.4-10.6, a loli ke kala mai ke kala ʻole a i ka uliuli. Ke hoʻohana ʻia, hoʻomākaukau pinepine ʻia ia i loko o kahi hopena ethanol 0.1% 90%. Hoʻomākaukau pinepine ʻia me nā hōʻailona ʻē aʻe e hana i kahi hōʻailona hui mālie e hoʻoemi i kona pae hoʻololi kala a ʻoi aku ka maopopo o ka nānā ʻana.

Hoʻohana pinepine ʻia ka Thymolphthalein ma ke ʻano he mea hōʻailona waikawa-kumu, me ka pae loli kala pH o 9.4 a 10.6, a me ka loli kala mai ke kala ʻole a i ka uliuli. Ke hoʻohana ʻia, hoʻomākaukau pinepine ʻia ia ma ke ʻano he hopena ethanol 0.1% 90%, a hui pinepine ʻia me nā mea hōʻailona ʻē aʻe e hana i kahi mea hōʻailona hui ʻia e hoʻohāiki a maopopo hoʻi kona pae loli kala e nānā. No ka laʻana, ʻo kahi mea hōʻailona i hana ʻia ma ke kāwili ʻana i kahi hopena ethanol 0.1% o kēia reagent me kahi hopena ethanol 0.1% o ka phenolphthalein he kala ʻole ia i loko o kahi hopena waikawa, poni i loko o kahi hopena alkaline, a rose ma ka pH 9.9 (kiko hoʻololi kala), he mea maʻalahi loa ke nānā.
Hoʻopili ʻia nā huahana i loko o ka ʻeke, 25kg / pahu
