I have tried to do a lot of research and didn't succeed to find the boiling point and density of LSD. I would want to know this information. In addition, I can't use Clausius–Clapeyron equation because I don't have the data that I would need to use that equation.

$\begingroup$ Why can't you use the Clausius-Clapeyron equation? $\endgroup$– Curt F.Feb 14, 2016 at 4:02

$\begingroup$ @CurtF. Because I don't have the data that the equation needs. $\endgroup$– Pichi WuanaFeb 16, 2016 at 14:28

$\begingroup$ I think your question would be better if you explained that detail in the text of the question itself. $\endgroup$– Curt F.Feb 16, 2016 at 15:22

Lysergic acid diethylamide doesn't boil. It decomposes. The density is $1.2 \pm 0.1~\mathrm{g~cm^{-3}}$.
Data can be found at ChemSpider. There's a predicted boiling point of 541°C. However, lysergic acid decomposes at its melting point of about 240°C (CRC Handbook of Chemistry ad Physics, 64th ed.). This suggests that lysergic acid diethylamide does not have a real boiling point - at least at normal pressure.

1$\begingroup$ The statement about the boiling point is mainly common sense, given the structure and molecular weight of lysergic acid diethylamide. An additional argument is that lysergic acid decomposes at its melting point of about 240°C (CRC Handbook of Chemistry ad Physics, 64th ed.). The predicted boiling point of LSD is above 500°C[1] what is far above this temperature. The densitiy can also be found at[1].

2$\begingroup$ Concur, the decomposition is common sense, but supporting the argument with detail is a good idea. I recommend editing your answer to include the data and references of your comment. $\endgroup$– hBy2PyFeb 14, 2016 at 17:29

1$\begingroup$ … that's for lysergic acid. LSD itself (lysergide) has m.p. 80–85 °C (tartrate: 198–200 °C), no b.p. (ever measured?), as expected (Merck Index). $\endgroup$– mykhalOct 21, 2018 at 17:41
