Videla sem videoposnetek, vendar me zanima predvsem proizvodnja v velikem obsegu, pridobivanje 6 l kloroforma na ta način ni ravno poceni in učinkovito. Verjetno bom poskušal DCM dodatno klorirati v kloroform.

Na koncu sem dobil zelo zelo temno organsko plast z DCM. To sem nato destiliral v vakuumu, s čimer sem odstranil DCM, nato pa je nastalo rumeno olje. To je bilo čez noč zamrznjeno in prvič je bilo treba manipulirati, da je kristaliziralo, drugič je bilo 60 g trdne xtal mase žvepleno obarvane in dišeče po kafri.

@jokerr Mislim, da gpattona to ne zanima. Prosil sem za tolikšno pomoč in zdelo se je, da samo čakajo, da se razočaram, nato pa razorožijo jezik z obtožbo, da ne upoštevam postopka. Imam DM op in brez odziva.

Imam originalno forenzično pisanje. Morda bo osvetlil nekaj svetlobe. Ta pisanje je pošteno pes sranje tukaj.

Zdi se, da je razmerje med benzaldehidom in butanonom 1 : 4,44

Pozdravljeni. to pomeni, da morate združiti izvlečke, dodati vodno raztopino NaHCO3 in jih ekstrahirati (da, tekoča/tekoča ekstrakcija), nato pa ločiti plasti. Po tem postopku morate preveriti pH organske raztopine. Ta mora biti nevtralna (pH 6,5-7,5).

Pozdravljeni, imam vprašanje. Vse je jasno, toda kako to velikansko stvar segreješ na 55°, ali bo reakcija+mešanje pri veliki hitrosti sama ustvarila toploto?

V izvirnem postopku twodogs se uporablja perborova kislina, izdelana in-situ iz ocetne kisline & natrijevega perborata. Perborova pot je nekoliko neredna in zahteva filtriranje

Enkrat sem uporabil performinsko kislino in je delovala, vendar ne tako dobro kot perocetna kislina.

Zagotovimo vam lahko vodikov peroksid, vendar s koncentracijo 6 %.

Ali lahko kot šaržni reaktor uporabimo magmetični stiropor s funkcijo segrevanja in bučko ali kakšno drugo alternativo za šaržni reaktor ?

Ta metoda je videti super, otc poceni kemikalije.
Zakaj drag dcm, medtem ko kloroform obstaja. Če želite dolgotrajno kloroform, boste razumeli, da je izdelava kloroforma delo, ki ga morate opraviti.
Metoda zapisa, ki se deli tukaj, je popolna, kaže, da jo je napisal strokovnjak. Zanima me, ali obstaja kakršen koli videoposnetek o tej metodi. Tnx za delitev tega lepega pisanja up willi

Donosi kloroforma iz belila so grozni in bi trajalo celo večnost, da bi naredili spodobno količino. Uporabite toulen

Da, tudi jaz podpiram, ta celotna sinteza deluje zelo dobro.
