Gospodje, naredil sem ta poskus in ga segrel na 125 stopinj, ker se fosforjeva kislina segreje na 130 stopinj, nastane fosfatni vodikov plin (strupen). Ali obstaja kakšen način, da se temu izognemo?

lahko uporabite absorpcijo PH3 z NaClO in NaOH
H3PO2 se uniči pri 170 C

ali lahko namesto hipofosforne kisline uporabim 57-odstotno hidriodno kislino ?

Pozdravljeni, ali je kakšna razlika, če v tem receptu uporabim sudoefedrin ?
Hvala.

Različna razmerja za efedrin in psevdo.

You want a molar equivalent , these are hypothetical amounts, but say the the 6g of ephedrine is 20mmol of one mol of ephedrine then you'd want 20mmol equivalent of pseudo.im by no mean a pro and have never even looked up the molecular weight of either of them put that's the idea .
There's a post on here somewhere I believe from patten that is very detailed and informative about the subject definitely look it up because this is something that is very important in all reactions.

Pozdravljeni, imam vprašanje: ali bi lahko namesto joda uporabili kalijev jod? Ker je kalijev idodin veliko lažje kupiti.

Pozdravljeni, ne. Te snovi imajo različne kemijske lastnosti.

Za izdelavo joda lahko uporabite potasijev jod. To lahko storite v lenobnem nedeljskem popoldnevu.

Pozdravljeni, ne, ne morete uporabiti niti jodove niti fosforne kisline

Za odgovore se obrnite na strokovnjake, saj mi ni uspelo in sem porabil veliko denarja in materiala.

Učiteljica, ali lahko namesto tega uporabim DCM brez destilacije in preidem neposredno v preveliko količino vodikovega klorida?

You can do this, but it is better to extract into the water layer when acidification and evaporate part of the water. You can use aq. HCl
