Мога ли да използвам само кристали KI, с изключение на тези на йодон, в този синтез, знаете ли? Мога да екстрахирам йод от този KI, но това, което прочетох ...

Защо сте използвали dcm, може ли това да се направи без dcm? Също така не е ли малко прекалено да се използват 12 г I2 за 6 г ефедрин?

Можете да използвате петролен етер, бензол или толуол

Мога ли да използвам ксилол вместо DCM?

На кой етап ще се генерира фосген?

При него няма да се получи фосген. Ще има газ фосфороводород, ако е повече от 130. Бъдете внимателни с това.

Да! :). Когато правя този синтез, ако сложа PVC маркуч от кондензатора към газов капан, пълен с натриев карбонат и активен въглен, какво мога да направя, за да предотвратя от газовия капан засмукването на водния разтвор обратно към реакционната бутилка? Имате ли идеи, Ръководство?

Може ли някой да ме свърже с метод на едно гърне, при който мога да получа всички материали лично. Idc ако накрая се окажа само с някакъв мръсен метамфетамин просто търся проект, докато съпругата е извън града за уикенда.

Колко мл трябва да бъде стъкленият балон и колко трябва да бъде обратният кондензатор? Можете ли да отговорите?

За какъв балон става дума? Стандартен рефлуксен кондензатор на Алианс, среден размер.

В списъка има NH4Cl и H2SO4. Къде точно се използват те в синтеза? Благодаря за отговора.

Ammonium Chloride and Sulfuric Acid are combined to produce Hydrogen Chloride. Which is a gas that is used to turn the freebase into a hydrochloride salt. It is used towards the end of the video.

if o-xylene this is bad idea (B.P. 144C)
better petroleum ether, diethyl ether, benzene, toluene etc.

Ако при приготвянето на свободна основа добавя вода и hcl, за да подкиселя свободната основа, отделя водния слой и напълно изпаря водата, ще се появи ли накрая сол? На теория хлороводородът не е необходим?

When the free base extracted with DCM, you can use aqueous HCl for obtain salt after evaporation

can phenylpropanolamine be used instead of ephedrine in this synth?

Yes. If you have a supplier, send me a DM. The only problem is that the yield may be less than with the methylated version.

Seen that chemical on an Asian (India) chemical company for good price

Think that chemical is being used as an animal dog medicine

Swim had done this "red, white, blue" process with 6g E, 6g I, 3 g Rp and a couple of mls of D-H20 in a heat proof Corona beer glass bottle as a RXN vessel, a rubber stopper with airleak-proof connection with 5 foot tubing vertical and a punch balloon as a condenser, used a portable rice cooker & sand bath as heat source ~100-120C for 24 hours

Long Wet Reaction

Off heat to cool. Add 100 ml D-H20 . Filter Rp (**WASH OUT THE RP WITH HOT ACID, HOT ALCOHOL, HOT ACETONE, lukewarm water** good as new)
Add NaOH base solution till pH 12 A WHITE SLURRY WILL APPEAR
Extract with a NP fuel several times
Wash NP fuel/chilli with baking soda solution and then a D-H20 wash
Dry with drying agent for minutes and filter

Get a shot glass of D-H20 and drop 2-3 drops of HCl (or sulfuric acid) in it. Put this shot glass water with the NP/chilli and shake

Repeat several times

Extract water/chilli and evaporate on LOW heat

Speed a few hundred milligrams but good



* Swim got a VERY small percent yeild doing this method :(

Why did swim with 6 G of pseudoephedrine ended up with just a few hundred milligrams of speed ?! :(

Think you can make synthetic Ephedrine from propiophenone, there is a video

And don't seem very complicated

Can I do this synthesis at 140 Fahrenheit for 48 hours and get the same result ?
