Effect of Sweeteners on Viscosity and Particle Size of Dilute Guar Gum Solutions
The effects of some synthetic sweeteners on the rheological and physical properties of guar gum in dilute solutions were investigated.Measurements include the determination of intrinsic viscosity and the particle size, surface weighted mean [D3, 2], volume weighted mean [D4,3] and specificsurface area ofguar gum andsyntheticsweeteners mixtures. T...
متن کاملEffect of concentration on the viscosity of dilute solutions.
if the solute is a nonelectrolyte. TJo is the viscosity of the pure solvent. Considerable experimental and theoretical effort has been devoted to a determination of the coefficient ai, the so-called intrinsic viscosity, for susp'ensions of particles of various shapes since Einstein's [1] 1 original hydrodynamic treatment of sphcres. In these hydrodynamic theories, al is a measure of the disturb...
متن کاملExperiment 37. Intrinsic Viscosity: Chain Linkage in Polyvinyl Alcohol
While the basic chemical structure of a synthetic high polymer is usually well understood, many physical properties depend on such characteristics as chain length, degree of chain branching, and molecular weight, which are not easy to specify exactly in terms of a molecular formula. Moreover, the macromolecules in a given sample are seldom uniform in chain length or molecular weight (which for ...

متن کاملFabrication of Polyvinyl Alcohol/Kefiran Nanofibers Membrane Using Electrospinning
The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...
