| hana hana | 1. Loaʻa mai ka pilina o ω,ω,ω-trichlorotoluene me ka hydrogen fluoride anhydrous. ʻO ka lakio molar o ω,ω,ω-trichlorotoluene i ka hydrogen fluoride anhydrous he 1: 3.88, a ua lawe ʻia ka hopena ma kahi mahana o 80-104 ° C. Ma lalo o ke kaomi o 1.67-1.77MPA no nā hola 2-3. ʻO 72.1% ka hua. No ka mea maʻalahi a maʻalahi ka loaʻa ʻana o ka hydrogen fluoride anhydrous, maʻalahi ka hoʻoponopono ʻana i nā mea hana, ʻaʻohe kila kūikawā, haʻahaʻa haʻahaʻa, kūpono no ka ʻoihana. Loaʻa mai ka pilina o ω,ω,ω-toluene trifluoride me antimony trifluoride. Hoʻomaʻamaʻa ʻia ka ω ω ω trifluorotoluene a me antimony trifluoride i loko o ka ipu hao, a ʻo ka distillate he trifluoromethylbenzene crude. Holoi ʻia ka hui ʻana me 5% hydrochloric acid, a ukali ʻia e 5% solution sodium hydroxide, a hoʻomehana ʻia no ka distillation e hōʻiliʻili i ka hakina 80-105 °c. Ua hoʻokaʻawale ʻia ka wai papa luna, a ua maloʻo ka wai papa lalo me ka calcium chloride anhydrous a kānana ʻia e loaʻa ai ka trifluoromethylbenzene. ʻO 75% ka hua. Hoʻopau kēia ʻano hana i ka antimonide, ʻoi aku ka kiʻekiʻe o ke kumukūʻai, ma ke ʻano maʻamau wale nō i nā kūlana ʻoihana e hoʻohana ana i ka maʻalahi. ʻO ke ʻano o ka hoʻomākaukau ʻana, ʻo ia ka hoʻohana ʻana i ka toluene ma ke ʻano he mea maka, e hoʻohana mua i ke kinoea chlorine ma ke alo o ka catalyst side chain chlorination e loaʻa ai ka α,α,α-trichlorotoluene, a laila e hana me ka hydrogen fluoride e loaʻa ai ka huahana. |
