The paper presents some results on the ability of palm oil polyol to replace petroleum-based in polyurethane (PU) synthesis. In this study, with amine functionality hydroxyl value (OH value) between 240 -253 mg KOH/g was used as component conventional polyol. Four different formulationsof coating have been prepared using pre-polymer process namely PU1, PU2, PU3 and PU4 isophorone diisocyanate r...

Diabetes is associated with increased risk of cardiovascular disease, coronary heart disease, stroke, acute myocardial infarction, blindness, and renal failure. Strategies to reduce their occurrence are an essential focus of patient care. More than one pathogenic process is involved, and genetics influence the risk. Hyperglycemia is a factor in the development of microvascular and possibly macr...

The secondary hydroxyl group involved in the oxidation, and the cis-vicinal secondary hydroxyl group, must have a D configuration jvith respect to t,he primary alcohol group adjacent to the site of oxidation. This specific mode of otida,tion facilitated the synthesis of several new ketoses. In a series of papers, Hudson and Richtmyer and their a.ssociates described the microbiological synthesis...

The effect of sodium tetraborate (Na(2)B(4)O(7), borax) on the thermal property of frozen aqueous sugar and polyol solutions was studied through thermal analysis. Addition of borax raised the thermal transition temperature (glass transition temperature of maximally freeze-concentrated solutes; T(g)') of frozen sucrose solutions depending on the borax/sucrose concentration ratios. Changes in the...
