High ammonia (HA) natural rubber latex (NRL) is generally very sensitive at lower temperature and will form big rubber lumps after the freezing and thawing processes.
The growth of ice crystals in an aqueous medium during freezing causes the rubber particles to move closer together and thus disrupts the protein cloud surrounding the latex particles.
The broken protein cloud causes rubber particles to coalesce and form big lumps after the thawing process.
However, this phenomenon did not occur when potassium oleate (PO) was incorporated into the HA NRL medium.
PO acted as a colloid stabiliser by means of adsorbance at the rubber latex surface, thus preventing the coalescence of rubber particles from occurring.
This study investigated the effect of PO loading (0, 0.1, 0.2, 0.3, 0.4, and 0.5 phr) on the colloid stability of HA NRL after being subjected to both freezing and thawing.
These latex mixtures were frozen by cooling it at − 4 °C for 24 h and thawed by allowing them to stand at room temperature for 1 h followed by heating at 40 °C for another hour.
The results obtained showed that the PO improved the colloid stability of HA NRL in terms of morphological properties, viscosity, and mechanical stability time values.
Particle-size distribution of latex mixtures, however, did not vary even after freezing.
Potassium oleate in slightly alkaline solution was hydrogenated for up to 7 hr with Rufert nickel catalyst at 150C and 20 kg/sq cm pressure.
With 1% catalyst, the iodine value dropped by 12 units in the first hour, and only slightly thereafter.
With 2% catalyst there was a drop of 24 units in iodine value in the first hour, a steady state for the next 3 hr, and a second sharp drop of 30 units prior to the seventh hour.
Samples of fat hydrogenated over 1% catalyst for 3 hr and 7 hr respectively were analyzed by gas-liquid chromatography, thecis andtrans monoenes were separated by argentation thin-layer chromatography, and the positional isomers in each were determined by oxidation of the total fraction to dicarboxylic acids, which were then estimated by GLC.
Apart from double-bond saturation during the first 3 hr of hydrogenation, extensive double-bond migration yielded 23.5% oftrans 8- to 13-monoene, accompanied by small amounts only of positionalcis monoenes other than the starting material.
After 7 hr of hydrogenation, extensivecis tocis isomerization occurs, accompanied by lesscis totrans shift; thecis:trans ratio for each monoene consequently tended toward 1:1.
The results are explained on the sorption mechanism of hydrogenation and suggest that soap hydrogenation, involving catalyst poisoning, may represent a magnified version of normal fat hydrogenation.
Different microemulsions were prepared with and without mefenamic acid (MFA).
The base microemulsion was mainly composed of distilled water; the aqueous phase, propylene carbonate; the oil phase, potassium oleate; the surfactant, and finally di-ethylene glycol; the cosurfactant.
The effect of mixing ionic (potassium oleate) with nonionic surfactant was investigated via constructing the phase diagrams of such systems.
Changes in conductivity and viscosity of the freshly prepared microemulsion over time were monitored as an indication for the stability of the microemulsion.
Measurements were carried out at room temperature, after a freeze-thaw cycle and also after storage for 3 days at 60°C, where the latter is treated as an accelerated test for the time-temperature effects on the stability of a microemulsion.
Potassium oleate was found that a set of surfactants, instead of a single surfactant, and inclusion of cosurfactant resulted in a broader region where a stable microemulsion is predominant.
At a mass ratio of 1:2 of potassium oleate to Tween-20, O/W microemulsions were found to have maximum stability among all examined systems, under the accelerated test, such that they have a minimum portion of combined surfactants and cosurfactant of 60 wt% and maximum of 80 wt%.
With the aforementioned specifications, no phase separation and neither significant change in the conductivity nor in the viscosity was observed in any of the examined systems after subjecting them both to the accelerated and freeze-thaw cycle test, indicating that such systems were thermodynamically stable.
Samples of micro emulsions passing previous tests were further subjected to an acidic medium by dispersing 1 g of MFA-containing microemulsion in 10 g HCl solution (pH 1) in a shaking water bath at 37°C, for a 6 hour period.
The maximum solubility of MFA in a stable microemulsion was approximately 5 wt%, evaluated at room temperature.
