@G.Patton Glede na barvo CuCL2 sklepam, da ne gre za CuCL2, temveč za bakrov (II) klorid dihidrat.

Ali prav razumem, da je to bakrov (II) klorid dihidrat (CuCL2 2H2O) s CAS: 10125-13-0?

V opisu mojega izdelka piše, da je običajni CuCL2 rjavkaste barve, medtem ko je CuCL2 Dihidrat modro-zelenkaste barve, kot je prikazano na sliki. Malo sem zmeden, ker je na njem napisano CuCL2, barva pa je CuCL2 2H2O.

Da, imate prav. Vseeno boste uporabili CuCl2 z vodo. Lahko vzamete CuCl2*2H2O in v njej preštejete enako količino CuCl2.

Odlično, to sem predvideval. Najlepša hvala!

@Curiousonion je potrjeno.

Všeč mi je posodobitev prispevka @William Dampier

Ali sem korekten s predpostavko, da moram do 4. koraka uporabiti največ 50 % prostornine reaktorjev?

V 20-litrskem reaktorju bi to pomenilo, da je RM 10 l, kar pomeni, da lahko naložim do

Pravilno, prostornina reaktorja mora biti med reakcijo ~30-50 % prazna. To je zaradi varnostnih razlogov.

Gotcha, torej lahko v 20-litrski reaktor brez težav naložim približno 475 g P2NP?

50 % prostornine reaktorja pred eksotermno reakcijo in 70 % prostornine med eksotermno reakcijo, vključno s penjenjem?

da, ali mislite 50 in 70 % naloženega prostora?

Mislim na 50 % naloženega prostora, tako da se lahko med eksotermno reakcijo razširi na največ 70 %, če bi se kadilo.

Domnevam, da če naložim 70 %, se lahko precej približa, če se razširi na 90 %.

Kaj menite?

Ali obstaja razlika med tem CuCL2 2H2O in tem CuCL2 ali sta enaka

Lahko ga preprosto kupite:

Dihidrat bakrovega (II) klorida (CuCL2 2H2O) s CAS: 10125-13-0

Ima enak učinek kot običajni CuCL2, stane pa manj, saj lahko uporabite enako maso/volumen

Vabljeni!
Če boste več iskali, boste našli tistega, ki sem ga napisal zgoraj, v trgovinah EU, brez omejitev
CAS je drugačen, torej gre za drugo kemikalijo. Predvidevam, da gre za navaden CuCL2 in ne CuCL2 2H2O

Pozdravljeni,

Vprašanje,

Ko se amfetaminsko olje kristalizira z žveplovo kislino, je čas, da amfetamin filtriramo z Buchnerjevim lijakom, moje vprašanje je. Katera vrsta filtrirnega papirja je priporočljiva za to?

Iščem na primer filter z naslednjimi lastnostmi, ali je to dobro priporočilo?

Lastnosti filtra:
Filtrirni papirji iz tissue papirja
Trdi filtri - čas filtriranja 140 sekund (zadrževanje> 2 µm). Počasno filtriranje.
Gosti filtri za fine in zelo fine usedline.
Teža: 85 g/m2.
Debelina: 0,17 mm.
Čas filtriranja: 140 s.
Zadrževanje:> 2 µm.


Z največjim spoštovanjem

1. Material:
Generally, tissue paper is not recommended for chemical filtration, especially in organic chemistry, as it may not provide the necessary chemical resistance and could introduce impurities.

3. Retention:
This retention level is suitable for filtering out larger particles, but if the amphetamine salt crystals are smaller than this size, they may pass through the filter. For crystallization processes, you typically want a filter paper that can retain smaller particles, ideally in the range of 1 µm or less.


4. Weight (85 g/m²) and Thickness (0.17 mm):
a relatively dense filter paper, which may be good for fine filtration but could also slow down the process. Thicker filter papers tend to have lower flow rates

Recommendations​

Quantitative Filter Paper:
Look for papers with a retention size of 1 µm or less, which would be more suitable for filtering fine crystals.


Buchner Funnel Filtration:
Whatman filter paper or similar brands that are specifically designed for vacuum filtration. These papers are available in various grades, including those with finer retention capabilities (e.g., Whatman Grade 1 or Grade 2).

dobro vprašanje... tudi mene zanima..
dejansko uporabljam to

vendar ne vem, kaj je to lol

Videl sem veliko vrst filtrov "kvalitativnih" ali "kvantitativnih" in v vsaki kategoriji različica "počasi" "srednje" in "hitro"...
Katera je najboljša? :p

Quantitative Filter Paper
Specification: 9.0 cm
The second image has a table with various specifications, likely describing different types of filter paper based on attributes like thickness, pore size, or filtration speed.

BUMP!

Vprašanje,

Trenutno delam naslednjo lestvico sestavin:

IPA 2:1, 3,6l
NaBH4, 348g
P2nP, 200g
CuCl2, 20g + 40ml H2O
NaoH 25%, 1,6l

Izvedel sem, da je lestvica linearna, zato sem prišel do teh meritev.

Zdaj pa vprašanje: če bi vse sestavine ohranil na enaki lestvici, le P2nP bi povečal za 300 g, kakšen bi bil rezultat?

Lep pozdrav

Vse je treba sorazmerno povečati
Lahko pa poskusite povečati samo težo p2np in sami boste videli, kaj se bo zgodilo
Nato nas lahko tukaj seznanite s svojimi rezultati, tako da se bomo vsi naučili kaj novega.
Nadaljujte z delom
