Tjena r lite sugen p att frska omvandla cbd till THC
Har lite svrt att fixa eter och svavelsyra s tror ni att det skulle rcka med citronsyra blandat med ttiksyra?
enligt wiki kan man f ner pH till runt 2,5 med endast citron och ttiksyra. Tror ni det rcker fr att isomizera cbd till THC?
Nr man ltit det reagera i syran ett dygn eller tv tnker jag att man hjer pH vrdet med propplsare eller bakpulver till runt ph 7
Sen funderar jag p hur man ska separera THC frn resten av srjan. Mste man kpa eter? Eller tror ni att man kan fixa fram ntt med hjlp av aceton?

Cannabidiol (CBD), the main cannabinoid constituent of fibre hemp has been converted (isomerized) to delta-9 and delta-8-tetrahydrocannabinol employing a variety of conditions.
Many of these procedures require chemicals that are hard to come by such as dichloromethane (DCM) and boron trifluoride etherate.
The following is a simple and fast procedure for the synthesis of delta-8- or delta-9-THC from CBD:
Dissolve 1g of CBD in 10ml 0.005molar H2SO4 in glacial acetic acid.
Let solution stand at room temperature.
After 3 hours CBD has been converted into 52% delta-9-THC and 2% delta-8-THC.
After 3 days a mixture of 15% delta-9-THC, 54% delta-8-THC, 10% delta-8-iso-THC and 10% CBD has formed.
Work up:
Pour into water (100ml or more) and add cautiously with stirring (foaming!) enough sodium bicarbonate (15g should do) to raise the pH above 7. Extract with petrol ether, wash with water, evaporate solvent to get mixture of starting CBD and predominantly delta-9- or delta-8-THC with some other byproducts depending on the reaction time.
Can chromatograph on silica gel with 1 to 2% ether in petrol ether for purification.
CBD can also be converted into delta-9-THC with anhydrous ZnCl2 at 150 without solvent (perform reaction best in vacuum as product is sensitive to oxidation):
Heat 0.5g CBD with 0.09g anhydrous ZnCl2 under vacuum with stirring.
After 2 hours 40 to 50% delta-9-THC have formed.

fast detta verkar inte s farligt, lycka till! som sagt, verkar bli mycket jobb fr lite rka.
