ʻO 2,4-Difluorotoluene he mea hoʻohuihui. He wai kala ʻole me kahi ʻala ʻala kūikawā.
ʻO 2,4-Difluorotoluene ka nui o nāʻoihanaʻoihana. Hiki ke hoʻohana ʻia no ka hana ʻana i nā mea hoʻonaninani kiʻekiʻe, nā kala, nā resins, a me nā surfactants.
Nui nā ala e hoʻomākaukau ai i ka 2,4-difluorotoluene. Loaʻa kahi ʻano hoʻomākaukau maʻamau ma ka hoʻopili ʻana i ka toluene me ka hydrogen fluoride. ʻO ka hopena maʻamau e hana ʻia i loko o ka māhele kinoea, a ma lalo o ke ʻano wela a me ke kaomi kūpono, ma o ka hana a ka catalyst, ua pani ʻia ka hydrogen atom ma ke apo benzene i loko o ka mole toluene e ka fluorine atom e hana i 2,4-difluorotoluene. .
ʻO ka ʻike palekana o 2,4-difluorotoluene: He wai hiki ke puhi ʻia i ke ahi ke ʻike ʻia i kahi lapalapa ākea a wela paha. Pono e mālama i ka pale ʻana mai ka pili ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu i ka wā e lawelawe ai a hoʻohana ʻia paha. Pono e mālama pono ʻia ka ʻōpala i mea e pale aku ai i ka haumia i ke kaiapuni. I ka wā e hoʻohana ai, pono e hoʻokō i nā kaʻina hana palekana kūpono a me nā hana pale e hōʻoia i ka palekana pilikino a me ka palekana o ka nohona.
