Senhores, fiz este experimento e o aqueci a 125 graus, porque o ácido fosfórico é aquecido a 130 graus, e haverá gás hidrogênio fosfato (tóxico). Há alguma maneira de evitar isso?

você pode usar a absorção de PH3 com NaClO e NaOH
H3PO2 destruído a 170 C

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.
Sincerely B

Olá, tenho uma dúvida: em vez de iodo, poderia ser usado iodo potássico? Porque o iodo potássico é comprado com muito mais facilidade.

Olá, não. Essas substâncias têm propriedades químicas diferentes.

Você pode usar o iodo potássico para produzir iodo. Isso pode ser feito em uma tarde preguiçosa de domingo.

Peça respostas a especialistas, pois não consegui e gastei muito dinheiro e materiais.
Bahasa Indonésia:Para esse estágio de destilação, o que é necessário para o próximo processo?
Bahasa Indonesia:Se o resultado do vapor da destilação ou o restante do material que é aquecidoSe o resultado do vapor da destilação ou o restante do material que é aquecido 🙏

Professor, posso usar DCM sem destilação e ir diretamente para o cloreto de hidrogênio com excesso de peso?

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

You must control the boiling to avoid problems with the volcano. Use boiling chips. Change the weight you need according to the specified proportions.

Hello, I have a question
I got a good result through this work
I have a few questions
1. It was heated to 100 degrees in hypophosphoric acid + ephedrine + iodine
There was a weight loss for the result. Would 110 degrees be okay?
2. Is it okay to calculate the capacity twice or three times for the mass production process and run the process? If so, how should we calculate the temperature and time of the reflux cooler?
3. I'm most curious about the process for number two. Simply put, if you start with six grams of ephedrine, if you put two or three times the dose in every process and manufacture it
I wonder what the temperature and time of the reflux cooler should be
4. The process of reflux cooler refers to the process in hypophosphoric acid + ephedrine + iodine

The temperature can be 110 but longer in time
In this synthesis, phosphine is formed, therefore, an increase in the volume without ventilation hood is unsafe

Thank you for your answer
1. If you increase the volume, how much volume is appropriate?
2. If you increase the volume, how should you determine the time and temperature?
3. Why does it take longer than 100 degrees if you proceed to 110 degrees?
4.What is the appropriate temperature in your opinion?
