Organosolv pretreatment of oat husk using oxalic acid as an alternative organic acid and its potential applications in biorefinery

Phosphosulfonic acid as an soild acid supported on nanosilica extracted from rice husk in Polyhydroqinilion Synthesis

Phosphosulfonic  acid  as a  multi  solid site  was  easily  prepared  from  the reaction of ammonium  dihydrogen phosphate with chlorosulfonic acid in CCl4and for improved  its  catalytic activity  was  supported  nano Silica was  extracted from  husk  rice  contains  about 95%  of  Silica the  size of  extracted nano silica was  determined  by  SEM  efficiency of  this solid acid in four comp...

Recent Applications of Meldrum's Acid in Organic Synthesis

Reactions of Meldrum's acid and its derivatives in view of their application in synthesis of diaminofurans,ketenimines, amidoesters, triamides, and diionic compounds, observed during the last decade in our laboratory,are reviewed.

An Oxalic Acid Producing Penicillium.’

Oxalic acid formation by fungi has received the attention of several investigators since de Bary2 observed that the mycelium of Sclerotinia sclerotiorum became incrusted with an oxalate in its older stages. The most elaborate study of the problem was made byWehmer.3 His results were published in a series of twent,y-three papers. Tabulated data showing oxalic acid production under various condit...

Advanced Biofuels and Biorefinery Platforms A Novel Pretreatment Process Using Oxalic Acid on Waste Mushroom Medium for Production Fermentable Sugar and Ethanol

Cauliflower mushroom (Sparassis crispa) is well known as a brown-rot fungi selectively degrades heartwood of wood, and that has potential anticancer and immune enhancing activity; thus its production is increasing in Korea. The mushroom is cultivated artificially using plastic pots filled with medium material, such as lignocellulosic biomass and some additives. However, most of the medium remai...
