متن کاملFats and oils as oleochemical raw materials *
Vegetable oils and fats are important constituents of human and animal foodstuffs. Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a corresp...
متن کاملconstruction wastes as raw materials for geopolymer binders
it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...
متن کاملDetermination of chondroitin sulfate in raw materials by liquid chromatography.
A rapid method for the determination of chondroitin sulfate in raw materials was developed. The samples were finely powdered, dissolved in water, and injected directly into the liquid chromatograph. The method used a C18 column, a wavelength of 195 nm, and a mobile phase containing octane sulfonic acid. The method gave results that were slightly different from those generated by atitrimetric me...
