Separation of Thiourea and Ammonium Thiocyanate

open access: yesBUNSEKI KAGAKU, 1954
Ammonium thiocyanate and thiourea are interchangeable isomers. The authors found that treating a mixture of these two with mercuric chloride gives a precipitate of thiourea above pH 4, while the ammonium thiocyanate does not give precipitate below pH 6; thus, the thiourea is precipitated with mercuric chloride at pH 46 to separate from ammonium ...

Ultrasound-assisted thiocyanation of aromatic and heteroaromatic compounds using ammonium thiocyanate and DDQ

open access: yesUltrasonics Sonochemistry, 2008
Thiocyanation of various aromatic and heteroaromatic compounds has been achieved in the presence of ammonium thiocyanate (NH(4)SCN) and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in methanol solution under ultrasound irradiation. An ultrasonic probe of 24 kHz frequency has been used for this study.

Formulation of Gluten‐Free Biscuits Based on Tiger Nut, Dana, and Mixture of Avocado and Margarine: Nutritional Composition and Glycemic Index of Optimal Sample

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
This study aimed to develop a gluten‐free biscuit with a low glycemic index by completely replacing wheat flour with flours from three local plant foods (tiger nut, dana, and avocado). The methodology began with the production of tiger nut and dana flours and avocado paste followed by the mixing plan and obtention of 09 (nine) formulations. The optimal
