Ionic Liquid-Based Ultrasonic-Assisted Extraction of Alkaloids from Cacao (Theobroma cacao)

open access: yesChemical Engineering Transactions, 2018
Recent advances in the solid-liquid extraction have brought a large number of new techniques as ultrasonic assisted extraction (UAE). Different solvents such as alcohols, acetonitrile and chloroform are reported as extractors of added-value compounds ...

Factors Affecting the Catalytic Epoxidation of Olefins by Iron Porphyrin Complexes and H2O2 in Protic Solvents [PDF]

open access: yes, 2016
The catalytic epoxidation of cyclohexene by iron(III) porphyrin complexes and H2O2 has been investigated in alcohol solvents to understand factors affecting the catalyst activity in protic solvents.

Silver-Mediated Allylic Disulfide Rearrangement for Conjugation of Thiols in Protic Media [PDF]

open access: yes, 2016
Alkyl and aryl allyl disulfides are induced to undergo the desulfurative allylic rearrangement by silver nitrate in protic solvents at room temperature, thereby removing the necessity for the use of phosphines as thiophilic reagents.

Regenerated silk fibroin using protic ionic liquids solvents : towards an all-ionic-liquid process for producing silk with tunable properties [PDF]

open access: yes, 2012
We have shown that protic ionic liquids, pILs, are effective coagulation solvents for the regenerated of silk fibroin, RSF. We show that the choice of pIL has a dramatic effect on the composition of the RSF. Additionally the use of pILs as the coagulator

Bromination of Alkenes and Related Compounds by Use of Benzyltrimethylammonium Tribromide in Aprotic and Protic Solvents [PDF]

open access: yes
The reaction of alkenes and related compounds (1) with benzyltrimethyl-ammonium tribromide (BTMA Br_3) in aprotic solvents such as dichloromethane and chloroform gave 1, 2-dibromo adducts in fairly good yields.
