Hoʻohana kikoʻī
Nā mea waena pesticide; Hoʻohana ʻia ia ma ke ʻano he waena o puma, ʻo Gaicao kiʻekiʻe, jingwensha, jingquizalofop, alkyne ester a me nā lāʻau lapaʻau ʻē aʻe.
Hana hana
1. Ua hoʻomākaukauʻia ka P-chlorobenzoyl chloride e ka hopena o ka p-chlorobenzoyl chloride me ka anisole, a ma hope o ka hydrolysis a me ka demethylation.
2. Ka hopena o ka p-chlorobenzoyl chloride me ka phenol: e hoʻoheheʻe i ka 9.4g (0.1mol) o ka phenol i 4ml o 10% sodium hydroxide solution, e hoʻohui i 14ml (0.110mol) o ka p-chlorobenzoyl chloride dropwise ma 40 ~ 45 ℃, e hoʻohui i loko. 30min, a hana i ka wela like no 1H. E hooluolu i ka wela o ka lumi, kānana a maloʻo no ka loaʻa ʻana o 22.3g o ka phenyl p-Chlorobenzoate. ʻO 96% ka hopena, a ʻo ka helu heheʻe he 99 ~ 101 ℃.
Leakage lapaʻau pilikia
Nā hana palekana, nā lako pale a me nā kaʻina hana hoʻopau pilikia no nā mea hana:
Manaʻo ʻia e hoʻohana nā limahana lapaʻau ulia pōpilikia i nā mea hanu ea, nā lole anti-static a me nā mīkina lima pale ʻaila.
Mai hoʻopā a ʻaʻa paha i nā ʻōpala.
Pono nā mea hana a pau i hoʻohana ʻia i ka wā hana.
E ʻoki i ke kumu o ka leakage e like me ka hiki. E hoʻopau i nā kumu puhi ahi.
E koho ʻia ka wahi ʻōlelo e like me ka wahi i hoʻopilikia ʻia e ka kahe wai, ka mahu a i ʻole ka hoʻopuehu ʻana o ka lepo, a e hoʻoneʻe ʻia nā limahana pili ʻole i kahi palekana mai ka makani a me ka makani.
Nā hana palekana kaiapuni: loaʻa ka leaka e pale aku i ka haumia o ke kaiapuni. Kāohi i ka leakage mai ke komo ʻana i nā ʻauwai, ka wai ʻili a me ka wai lepo.
ʻO ke ʻano o ka mālama ʻana a me ka wehe ʻana i nā kemika leaked a me nā mea hoʻolei i hoʻohana ʻia:
Leaka liʻiliʻi: e hōʻiliʻili i ka wai leaka i loko o kahi pahu sealable e like me ka hiki. E hoʻomoʻa me ke one, carbon activated a i ʻole nā mea inert ʻē aʻe a hoʻoneʻe i kahi palekana. Mai hoʻolei i loko o ka ʻōpala.
Leaka nui: kūkulu i ka lua a ʻeli paha i lua no ka hoʻokipa. E pani i ka paipu wai. Hoʻohana ʻia ka ʻūhā e uhi i ka evaporation. E hoʻoneʻe i ke kaʻa pahu a i ʻole ka mea hōʻiliʻili kūikawā me ka pahū pahū, hana hou a lawe ʻia paha i kahi kahua lapaʻau no ka hoʻopau ʻana.
Nā lako pale pilikino:
ʻO ka pale ʻana i ka hanu: ke ʻoi aku ka nui o ka ea ma mua o ka maʻamau, e hoʻokomo i ka mask gas filter (half mask). I ka hoʻopakele ʻana a i ʻole ka haʻalele ʻana i kahi pilikia, pono ʻoe e hoʻokomo i kahi mea hanu ea.
Pale lima: e ʻaʻahu i nā mīkina lima pale ʻaila.
Ka pale maka: e hoʻohana i nā maka palekana kemika.
Ka pale ʻili a me ke kino: e ʻaʻahu i nā lole hana anti poison penetration.
