Taumahinga motuhake
Kei te whakamahia te reira i roto i te whakahiato waro, me te he takawaenga o te radiomiphene tarukino anti pākoko
Tikanga whakaputa:
1. I whakaritea te P-chlorobenzoyl chloride e te tauhohenga o te p-chlorobenzoyl chloride ki te anisole, whai muri mai i te hauwai me te demethylation.
2. Te tauhohenga o te p-chlorobenzoyl chloride ki te phenol: whakamemeha te 9.4g (0.1mol) o te phenol ki te 4ml o te 10% te wairewa konutai konutai, ka tapirihia te 14ml (0.110mol) o te p-chlorobenzoyl chloride ki te 40 ~ 45 ℃, tāpirihia ki roto 30meneti, ka tauhohe i te pāmahana kotahi mo te 1H. Matao ki te pāmahana rūma, tātari me te whakamaroke kia 22.3 karamu o te phenyl p-Chlorobenzoate. Ko te hua ko te 96%, ko te ira whakarewa he 99 ~ 101 ℃.

Pūmate hauora:
ka whakapataritari i te kiri. Ka mate kino te kanohi. Ka whakapouri pea i te waahanga manawa.
Whakatupato:
Horoia rawatia i muri i te mahi.
Kia mau i nga karapu whakamarumaru / kakahu whakamarumaru / motiti whakamarumaru / maru whakamarumaru.
A ape i te toronga o te puehu / auahi / hau / auahi / kohu / rehu.
Whakamahia ki waho anake, ki te whai hau pai ranei.
Whakautu aitua:
Mena kua poke te kiri: horoia ki te wai.
Ki te paheketanga te kiri: rapua te rongoa.
Tangohia nga kakahu poke ka horoi i mua i te whakamahi ano
Mena kei nga kanohi: Horoi marie ki te wai mo etahi meneti. Mena ka mau koe i nga arotahi whakapiri me te ngawari ki te tango atu, tangohia ki waho. Me horoi tonu.
Mena kei te mamae tonu koe i nga kanohi: tirohia te taote / taote.
Mena ka pokanoa te hau: whakawhitia te tangata ki tetahi waahi hau hou, kia mau tonu te noho manawa.
Mena kei te ahua kino koe, waea atu ki te pokapu whakakorenga / taote
Rokiroki haumaru:
Rokiroki ki tetahi waahi hau pai. Kia kati te ipu.
Me raka te waahi rokiroki.
Te tuku para:
Makahia nga ihirangi / ipu i runga i nga ture o te rohe.
Nga mahi awhina tuatahi:
Inhalation: ki te ngongohia, nekehia te manawanui ki te hau hou.
Te pa ki te kiri: tango i nga kakahu poke ka horoi marie i te kiri ki te wai hopi me te wai marama. Ki te kino koe, tirohia te taote.
Te kanohi: wehea nga kamo ka horoi ki te wai rere, ki te tote noa ranei. Rapua tonutia nga mahi hauora.
Te horomitanga: kakuhukuhu me te kaua e whakaruaki. Rapua tonutia nga mahi hauora.
Tohutohu ki te tiaki i te kaiwhakaora: whakawhiti te manawanui ki te waahi haumaru. Korero ki te taote. Whakaatuhia tenei pukapuka hangarau haumaru matū ki te taote i te waahi.
