Abstract: A viscoelastic polyurethane foam formed from a polyisocyanate and a polyol composition comprising palm olein-based polyol in an amount of 10% to 35% by weight of the total polyol composition and petroleum-based polyol in an amount of 65% to 90% by weight of the total polyol composition. The dissipation energy of the viscoelastic polyurethane foam is between 0.01 J to 0.30 J as calculated based on a hysteresis loop normalized a density of 40.80 kg/m3. This shows that the viscoelastic foam produced has an improved dampening property. The introduction of palm olein-based polyol into the production of viscoelastic foam does not affect the support factors and mechanical properties of the foam produced. The viscoelastic foams can be produced using an amount of up to 35% of palm olein-based polyol derived from palm olein or up to 25% of palm olein-based polyol derived from a mixture of palm olein and soybean oil by weight of total composition without any adjustment in the catalyst package.

Abstract: The present invention relates to a process for accelerated preparation of polyglycerol from crude glycerol using microwave irradiation as the heat element in the presence of soap as the catalyst. The process includes the steps of (a) heating the crude glycerol that contain soap to an elevated temperature for a certain reaction time by using a microwave technology, (b) acidifying the crude polyglycerol with mineral acid at a specific temperature and centrifuging acidified crude product obtained from step (b) at a specific temperature for a certain duration of time.

Abstract: The invention relates to a biodegradable functional fluid composition based on vegetable oil. This functional fluid suitable for lubricant, hydraulic and like fluid comprises palm olein and its by-product generated from fractionation of palm oil. The by-product is esterified by a hindered alcohol prior to blend together with palm olein and additive packages. The hydraulic fluid particularly suited for tropical climate with temperature ranging from 15-40° C.
