Kupu Whakataki
Ko te α-propyl-γ-butyrolactone (e mohiotia ana ko α-MBC) he whakarewa waro noa. He ahua wai kore tae me te hongi me te iti o te whakaetonga i te pāmahana rūma. Anei nga korero mo te α-propyl-γ-butyrolactone:
Kounga:
- He tino pai te whakarewatanga o te α-propyl-γ-butyrolactone, a ka taea e ia te whakakore i te maha o nga matū waro penei i te kapia, te peita me te paninga.
- Ko tenei lactone he kore e mura, engari ka taea e ia te whakaputa hau paitini i te wera nui.
Whakamahia:
- Ko te α-Propyl-γ-butyrolactone e whakamahia nuitia ana i roto i nga mahi ahumahi mo te whakarewa, te pahuka, te peita, te paninga, te whakapiri, me nga hua kirihou.
Tikanga:
- Ko te α-propyl-γ-butyrolactone i te nuinga o te wa ka whakaritea e te esterification o te γ-butyrolactone. I roto i tenei tukanga, ka tauhohe te γ-butyrolactone ki te acetone, ka taapirihia te taikaha o te waikawa pūhaumāota, waikawa pungatara ranei hei whakakōkī.
Mōhiohio Haumaru:
- I te wa e whakahaere ana i te α-propyl-γ-butyrolactone, karohia te whakapiri roa ki te kiri me te ngongo hau.
- Me whai i nga tikanga haumaru me nga ture i te wa e rongoa ana me te whakahaere i te α-propyl-γ-butyrolactone.
