Hale hana kaulana Terephthalaldehyde CAS:623-27-8
Hoʻohana nui ʻia kēia pūhui multifunctional ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis o nā lāʻau lapaʻau, nā dyes a me nā kemika kūikawā.He mea nui ia i ka hana ʻana i nā lāʻau lapaʻau e like me nā antihypertensives a me nā antifungals.He kuleana koʻikoʻi ka TPA i ka ʻoihana kala no ka mea he mea mua ia no ka hana ʻana i nā mea pena ʻālohilohi a lōʻihi no nā lole a me nā mea ʻē aʻe.Eia kekahi, hiki ke hoʻohana ʻia e hana i nā resins i hoʻohana nui ʻia i nā adhesives a me nā uhi.
ʻO kekahi o nā hiʻohiʻona nui o terephthalaldehyde kona maʻemaʻe kiʻekiʻe.Ke hana nei kā mākou huahana i kahi kaʻina hoʻomaʻemaʻe ikaika e hōʻoia i ka ʻole o nā haumia a me nā mea haumia, pēlā e hōʻoiaʻiʻo ai i ka hana ʻoi aku ka maikaʻi ma nā ʻano noi.Hoʻohui ʻia, hoʻoikaika mau kā mākou hui o nā chemists ʻike e mālama i nā kūlana kiʻekiʻe loa i ka wā o ka hana ʻana, e hiki ai iā mākou ke hoʻopuka i nā huahana kūpaʻa a hilinaʻi.
Hoʻomaopopo mākou i ke koʻikoʻi o ka hoʻomau i ka honua o kēia mau lā, a haʻaheo mākou i ka hoʻolaha ʻana e pili pono ana ka terephthalaldehyde me kēia mau waiwai.Hana ʻia kā mākou huahana me ka hoʻohana ʻana i nā hana kūpono e hōʻoia ana i ka hopena liʻiliʻi i ke kaiapuni.Eia kekahi, mālama pono mākou i nā lula palekana a pau e hiki ai ke mālama ʻia a hoʻohana pono ʻia ka TPA.
I ka hopena, ʻo terephthalaldehyde kahi mea maʻalahi, maʻemaʻe a hoʻomau i hoʻololi i nā ʻoihana.Inā makemake ʻoe e hoʻomohala i nā lāʻau lapaʻau ʻokiʻoki, nā mea ʻoniʻoni a i ʻole nā ʻili lole lōʻihi, ʻo kā mākou huahana TPA ka hopena kūpono.E hilinaʻi i kā mākou kūpaʻa i ka maikaʻi ʻoiai mākou e hoʻokumu i ka maikaʻi, ka hoʻomau a me ka palekana i kēlā me kēia pae o ke kaʻina hana.E hui pū me mākou i kēia lā e wehe i nā mea hiki ʻole ʻo terephthalaldehyde ke lawe mai i kāu ʻoihana.
