iconWaiwai

Aniani prismatic monoklinika (methanol). Hiki ke hoʻoheheʻe ʻia i ka wai wela, ka etanol (10 mg / ml), ether Hoʻohana ʻia ma ke ʻano waena no ka bisphenol biphenyl a me nā lāʻau ʻē aʻe. E like me ka antioxidant rubber

ʻO Methyl gallate, i kapa ʻia he methyl 3 a i ʻole methyl galloic acid, he lālā o ka papa o nā mea hoʻohui i ʻike ʻia ʻo nā esters galloyl. ʻO nā esters Galloyl kahi mea hoʻohui i loko o ka ester derivative o 3,4,5-trihydroxybenzoic acid. Mālama iki ʻo Methyl gallate (i ka wai) a me kahi hui waikawa nawaliwali loa (e pili ana i kāna pKa). Hiki ke loaʻa ka methyl gallate i ka peach a me ka pomegranate, kahi e hana ai i ka methyl gallate i biomarker hiki ke hoʻohana ʻia i kēia huahana meaʻai. ʻO ka Methyl gallate kahi hui phenolic. ʻO ia ka esh methyl o ka waikawa galic

iconPalapala noi

Noi o Methyl gallate ma ke ʻano he Photosensitizer anti-corrosion agents i ka hoʻomaʻemaʻe ʻana i ke kaʻina hana semiconductor, e koi ana i ke kūlana kiʻekiʻe me ka haʻahaʻa loa o nā metala e pale ai i ke kaapuni pōkole, e hoʻokele i ka mākeke ʻoihana uila i nā makahiki e hiki mai ana.
