The HCl i always dry with hair dryer on hot, and this time i finished the drying of the original 2.44g yield next to a heat source until the chips became hard and the weight stopped decreasing so my HCl should be dehydrated, Right?
The freebase i dry using a fan sometimes under the sun or i finish it in the oven but always got the same results but in this last experiment it was dried using just a fan.
About the color i think you misunderstood the book, this is from the book you posted part "On Harmaline. By J. FRITZSCHE."
Quote:Harmaline.—In the pure state it is quite colourless, but it is usually obtained of a somewhat brownish colour. To obtain it per fectly pure, it is diffused in water, acetic acid added until the greater portion is dissolved ; the filtered solution diluted, and precipitated with nitrate of soda, chloride of sodium or muriatic acid, up«n which it is again filtered, and the salt, after being washed with a solution of the precipitant employed, dissolved off the filter with lukewarm water. The solution is digested with animal charcoal till it possesses a light yellow colour; it is then precipitated, whilst still hot, by an excess of caustic potash. If the precipitate is not perfectly white, the same operation must be partially or wholly repeated ; and even then the preparation usually acquires a brownish tint on filtration and washing, especially when ammonia has been employed instead of potash to precipitate it. This colouring is undoubtedly owing to the influence of the oxygen of the atmosphere. The harmaline thus obtained forms broad laminar and scaly crystals of pearly lustre, which are of larger size the more slowly the precipitating agent was added.....
Hydrochlorate of Harmaline.—This salt is most readily obtained by precipitating the acetate or sulphate of harmaline with chloride of sodium, in a solution of which it is sparingly soluble ; but it is still more advantageous to use hydrochloric acid to precipitate the acetate of harmaline, in which the hydrochlorate of harmaline is nearly insoluble. If the salt, after washing it with hydrochloric acid, does not possess a light yellow colour, it may be purified by dis solving it in cold water, and again precipitating it with dilute hydro chloric acid. The hydrochlorate of harmaline forms long, slender, prismatic crystals of a yellow colour, which contain 4 equivs. water, part of which however it readily loses. It dissolves pretty easily in alcohol and water. On analysis, it yielded......
So it's obvious in the first line he is talking about the freebase and the alkaloids are finally precipitated with caustic potash or ammonia so it's the freebase not the HCL
And the second part "the hydrochlorate of harmaline forms long, slender, prismatic crystals of a yellow colour" and he also says that if the solution is not yellow it should be purified more
So the color of pure HCL harmalas is yellow
Another thing he mentioned is "which contain 4 equivs. water, part of which however it readily loses." So the HCl hydrate is easily dehydrated probably even without heat.
"Is this the end of our adventure? Nothing has an end. We came in search of the secret of immortality, to be like gods, and here we are... mortals, more human than ever. If we have not obtained immortality, at least we have obtained reality. We began in a fairytale and we came to life! But is this life reality? We are images, dreams, photographs. We must not stay here! Prisoners! We shall break the illusion. This is Maya. Goodbye to the holy mountain. Real life awaits us." ~ Alejandro Jodorowsky
