Ionic liquid with multi-SO3H groups was employed as a catalyst for facile preparation of 1,8dioxo-decahydroacridines via the one-pot condensation of various aldehydes, 1,3-diketones with aromatic amines or ammonium acetate. Various aromatic aldehydes were utilized in the reaction and in all situations the desired product were synthesized successfully. The described novel synthesis method propos...

Selective synthesis of carbamates from amines and dimethyl carbonate were studied in the presence of various ionic liquids as catalysts. The SO3H-functionalized ionic liquid was found to be the most active catalyst among the applied ionic liquids, and nearly 100% conversion and 95% electivity were achieved when using 1,6-hexanediamine as reactant. The acid functional ionic liquid catalyst syste...

In this protocol, 3-(2-carboxybenzoyl)-1-methyl-1H-imidazol-3-ium chloride [Cbmim]Cl and sulfonic acid functionalized pyridinium chloride [pyridine-SO3H]Cl as a new, reusable, and green Brønsted acidic ionic liquid (BAIL) catalyst were synthesized and successfully used for the one-pot ring opening of epoxide with sodium azide (NaN3) in water at room temperature. Epoxides under ring-opening easi...

Background: Curcumin is yellow pigment of tumeric, and, that is extracted from it lawsonia (2-hydroxy 1,4 naphtoquinon) is a natural product and it is extracted from henna. Ginger is a dried rhizomes gained from a plant called zingiber officinalea, which is extracted from the family of ginger. Material and Methods: This experimental study performed on adult male rats. Acute inflammatory edema ...

sunburn damage is a physiological disorder, which reducing pomegranate fruits quality and result to huge loss to the gardeners yearly. in this study, the effects of kaolin on maintaining fruit quality and decreasing sunburn damage of malas-e-torsh-e-saveh pomegranate was investigated. processed kaolin (surround® wp) with 0, 2.5, 5 and 10 % (w/v) was sprayed over the whole canopy and fruits at 4...

A patient is described who had a long history of abuse of kaolin and morphine mixture which ultimately proved fatal.

Results: Mean ACT value was 180±24 seconds. Femoral hemostasis was achieved with a double suture-based VCD deployment in 30 (67%) patients or a double VCD with cross-over balloon inflation in the remaining 15 (33%) patients. Bleeding after VCDs occurred in 15 (33%) pts. The kaolin-based dressing, activates the intrinsic blood coagulation pathway thus allowing for a short manual hemostasis perio...

The deflocculation effect of conventional additives to kaolin suspensions is evaluated from the results standard rheological measurements. Several widely used electrolytes (NaOH, Na2C03, Na2Si03, SHMP = sodium hexametaphosphate, and CMC = sodium salts of carboxymethylcellulose) have been tested. The optimal concentrations of these deffloculants, in respect to reaching the maximum reduction of i...

Goldfish were trained to press a lever. This response was followed by the delivery of a pellet of food. The fish were then allowed continuous access to the lever under controlled conditions, and their food intake was measured. Goldfish distribute their feeding responses fairly evenly over time, within the limits of the lighting cycle. Some fish eat mainly at night, some during the day, and othe...
