Ko te NVP te mea nui hei whakaputa i te polyvinylpyrrolidone, e whakamahia whānuitia ana i roto i ngā mara o te rongoā, te matū o ia rā me te ahumahi kai.

1. He whānuitia te whakamahinga i roto i ngā mea whakapaipai, ngā hopi horoi, ngā rongoā, ngā rauemi whakaahua-ā-tinana me ētahi atu mara

2. Mō ngā kirimi whakahāngai makawe, ngā patu huakita rongoā, me ētahi atu.

Ko te tukanga whakarite o te N-ethylene pheasone, tae atu ki ngā mahi e whai ake nei: 1. Kei roto i ngā whakakōkī maroke o te whakarite i te whakakōkī maroke he hiriwa whanariki, he konutai konumohe silicate, he waro pango mā, he ātete-ātete, me te maha-waikura. Ko te ōwehenga ko: 0.5 : 5 : 3 : 5 : 10; I roto i ēnei, ko ngā maha-waikura he ranunga e rima o te rima whakakōkī rua - me te waikura, te waikura tine, te waikura sex, me te hauhā konupora; He ranunga o te rima whakakōkī hauhā me te waikura, e rima whakakōkī rua - me te waikura tine, e rima whakakōkī rua - me te waikura konupora me te hauhā konupora. Ko te ranunga o te tuawhitu o ngā hauhā whakakōkī ko 0.2 : 1 : 2 : 1. Ko ngā mahi hanga o ngā whakakōkī maroke ko: whakaranua te hiriwa whanariki, te ātete-ātete, me te maha-waikura kia rite te ōwehenga, kātahi ka tāpirihia he 1 wā te nui o te wai kua whakakorea, whakatikatikahia te uara pH o te waikawa whanariki me te wai haukini ki te 6.5 ki te 7, kātahi ka tāpirihia te konutai silicine me te konutai siliconate kia rite te ōwehenga. He pango te waro mā, ka whakamahanahia, ka whakaohokia kia rite te otinga; ka whakaohokia ki roto i te kaukau wai, ka whakamaroke i te otinga kia maroke, ka maroke ki te 100-120 °C mō te 6 ki te 8 hāora, kātahi ka tunua mō te 3 ki te 5 hāora i te 400 ~ 450 °C. 2. Te Whakarite i te N-hydroxyethylpylpyline (NHP) 1) Whakaranua te γ-butanol, te etanoru kotahi, me te haukini i te ōwehenga o te 1.2: 1: 0.2, ā, ka tauhohe ki te 0.5MPa me te 40 °C. , Hangaia he takawaenga; 2) Tāpirihia te tātari ngota o te 0.1WT % me te 0.1WT % o te dilateyl dihal ether hei whakanui ake i te pāmahana ki te 180 °C kia maroke mō te 12 hāora i roto i te āhua pupuri; he aha te mea e whakaahuatia ana e te whakaahuatanga; he aha te mea e whakahuatia ana? Ko te tātari ngota he 10x, he 13X rānei. Ka tīpakohia tēnei tikanga hei 10x tātari ngota; 3) te whakatōtōtanga decompression, ko te korehau he 0.095MPa, ā, ka kohia te whakatōtōtanga o te pāmahana kohua o te 210 ki te 216 °C. Pyrodorrone; 3. Ko te tauhohenga maroke o te N-hydroxyetylpinol hei hanga i te kaute whakatōtōtanga i whiwhihia i roto i te whakarite o te N-hydroxyethylpinols ki te mamaoa, ka konatunatua ki te hau kawakore, ngā hau acetylene, me te hauota hei whiwhi i te ranunga rauemi mata hau. Ko te ōwehenga ranunga he 1: 0.5: 0.1: 0.1; Hangaia te ranunga rauemi mata hau i raro i te āhua o te tauhohenga moenga pumau o te whakakōkī maroke i te pāmahana o te 350 °C, te pēhanga o te 0.01MPa me te tere hau o te 50-300H-1, ā, ko te whakamaroke o te whakamaroke i roto i te tauhohenga moenga pumau ka whakamahanahia te whakakōkī ki te 390 °C. I muri i te tauhohenga maroke ki te taurite, ka tukuna te hua N-ethylene cephalopicone (NVP) mai i te tauhohenga moenga pumau. Ko ngā hau kawakore he haukini, he methylemine, he dihamine, he trothalmine, me te ethimine. Whakamahia te tikanga tātari chromatography hau, i runga i te γ-butthite hei paerewa ā-roto, ko te etanoru hei whakarewa, i tātarihia te hua N-ethylene cheedone i whakaritea mā tēnei tikanga, i tatau i te tere tahuritanga NHP, te whiriwhiringa NVP, te moni whiwhi NVP, o ēnei he wāhanga hau, o ēnei he wāhanga hau, o ēnei he wāhanga hau. Ngā tikanga whakamātautau chromatographic: te pūoko TCD, te pou kowiri tira, te otinga whakatika polyacetic glycol tannite dilate, kua utaina te hauota, te silicanerization 102 te rerekētanga mā, te pāmahana rūma hauhanga 280 ° C, te pāmahana pūoko TCD 165 ° C, ngā pou, ngā pou, ngā pou. Ko te pāmahana o te 190 ° C; i tatauhia mā te tātari chromatography hau: te tere tahuritanga NHP o te 92.8%, te whiriwhiringa NVP 91.5%, me te moni whiwhi NVP o te 85.6%.
