ʻO ka Spectroscopy Infrared (IR) waikawa Propionic
E hoʻohana i kahi spectrometer infrared no ka ʻike ʻana. Ma ka lawe ʻana i ka ʻike ʻana o ka waikawa propionic a me nā hui like ʻē aʻe ma ke ʻano he laʻana, e hoʻopili i kahi liʻiliʻi o ka hāpana waikawa propionic ma luna o kahi pellet potassium bromide a i ʻole e hoʻohana i ke ʻano kiʻiʻoniʻoni wai e hoʻomākaukau i kahi hāpana hoʻāʻo kūpono. A laila e kau i ka hāpana i loko o ke keena hāpana o ka spectrometer infrared. Hoʻopuka ka spectrometer infrared i ka mālamalama infrared. Ke hoʻomālamalama ka mālamalama infrared i ka hāpana, omo nā molekala hāpana i nā alapine kikoʻī o ka mālamalama infrared, e hana ana i nā hoʻololi pae ikehu vibrational a me ka rotational. Hoʻopili nā pilina kemika like ʻole i nā alapine like ʻole o ka mālamalama infrared, e hopena ana i nā piko absorption hiʻohiʻona i ka spectrum infrared. Loaʻa i ka waikawa propionic nā hui hana e like me ka waikawa carboxylic, e hōʻike ana i nā piko absorption hiʻohiʻona like i ka spectrum infrared (e laʻa, ʻo ka piko vibration stretching o ka hui waikawa carboxylic ma kahi o 1700 cm⁻¹). Ma ka hoʻohālikelike ʻana i ka spectrum i loaʻa me ka spectrum infrared maʻamau o ka waikawa propionic i ʻike ʻia, hiki ke hoʻoholo ʻia inā he waikawa propionic ka hāpana. Hiki ke hana ʻia kahi kuhi koʻikoʻi o ka nui o ka waikawa propionic ma muli o ka ikaika o nā piko hiʻohiʻona, akā ʻoi aku ka hoʻohana pinepine ʻia o kēia ʻano hana no ka nānā ʻana i ka qualitative.info@pulisichem.cn

Hāʻawi ʻo Shandong Pulisi Chemical Co., Ltd. i ka Propionic Acid (CH₃CH₂COOH, CAS 79-09-4)— he waikawa carboxylic kaulahao pōkole me ka maʻemaʻe 99.5% min, i loaʻa a hana ʻia i loko o ka hale no ka lako paʻa a hiki ke hahai ʻia. ʻO kā mākou waikawa propionic he wai maopopo a ʻawaʻawa me ka pale ikaika i ka ʻōpala a me ka bacteria, i hilinaʻi nui ʻia ma ke ʻano he mea mālama hānai, mea hoʻopaʻa ʻōpala meaʻai, a me ke kikowaena koʻikoʻi no nā uhi, nā lāʻau lapaʻau, a me ka synthesis kemika o kēlā me kēia lā. Hoʻoponopono mākou i nā māka a me nā ʻōpala: 200kg mau pahu plastik, 1000kg mau ʻeke IBC, a i ʻole nā ​​​​​​pahu ISO, me nā palapala piha (COA, MSDS, ISO, HALAL) e hoʻokō i ka hoʻokō honua. Me nā makahiki o ka ʻike hoʻokuʻu aku, hāʻawi mākou i ka maikaʻi mau, ke kumukūʻai hoʻokūkū, a me nā logistics hilinaʻi - ʻo kāu hoa hele no nā kauoha waikawa propionic nui ma ka honua holoʻokoʻa.
