Palm-based oleochemicals as inert ingredients in pesticide formulations

Bahan kimia agro memainkan peranan penting di dalam sektor pertanian. Dalam tahun 1995, pasaran bahan kimia agro di Malaysia adalah melebihi 289 juta ringit yang mana racun rumpai, racun serangga, racun kulat dan racun tikus adalah kira-kira 76%, 15%, 5% dan 4% daripada jumlah pasaran keseluruhan. Pada amnya, penyediaan formulasi racun perosak mengandungi dua komponen […]

Survey of the chemical and physical characteristic of some commercial Malaysian palm glycerin

Pengilang-pengilang Malaysia adalah berkemampuan menghasilkan gliserin berkualiti tinggi. Kebanyakan gliserin yang dihasilkan oleh pengilang Malaysia adalah mudah ditakrifkan dengan ketulenan yang konsisten. Semua sampel yang dikaji mempunyai ketulenan melebihi 99% dan oleh yang demikian boleh dikelaskan sebagai gliserin bergred halus, memenuhi piawaian ‘United State Pharmacopoeia (USP) atau European Pharmacopoeia (PH.Eur)’. Berkenaan dengan parameter kualiti seperti […]

Microbial degradation of flexible polyurethane foams by aspergillus niger and aspergillus terreus

The ability of the fungi, Aspergillus niger and Aspergillus terreus, to degrade palm-based flexible polyurethane foam was determined via the petri dish and shake flask tests. A dense fungal growth was detected by visual examination of foams inoculated on minimal nutrient agar/solution (MN)but not on the mineral salts agar/solution (MS). Both the palm-based and commercial […]

Determination of arsenic in palm glycerin using a graphite furnace atomic absorption spectrometer

A method for the determination of arsenic in palm glycerin using a graphite furnace atomic absorption spectrometer (AAS) was developed. Samples were dissolved in distilled water and injected directly into the graphite furnace AAS fitted with an arsenic electrode-less discharge lamp. The AAS furnace temperatures were set at 120oC, 800oC and 2400oC for drying, charring […]

Palm-based polyols and polyurethanes: two decades of experience

Emerging technological knowledge is leading into new ventures. One such of these is the conversion of vegetable oils to polymers to augment the use of petroleum products as the source of polymeric raw materials. Vegetable oils, such as palm oil and soyabean oil, now mainly used in the food industry, could offer alternative applications for […]
