“…Plastics industry from the petroleum feedstocks is facing serious condition because the demand is much higher than the production rate. Because of that, several industries try to shift from petroleum-based polymer to biomass-derived polymer [46]. Preparation of biopolymer using an atom transfer radical (ATRP) polymerization had been known as an environmental-friendly method because it could be conducted in mild condition.…”

Environmental pollution and global warming cause serious problems in human life. Since the demand for our human daily appliances had been increased by years, the organic chemical-based industries response that demand increment by increasing their production process. Because of that, the environmental pollution becomes worse and worse. Green chemistry thus was introduced to influence the chemical industries to strive for better environmental sustainability. Over 20 years, green chemistry principles have to influence the organic chemistry field especially as many researchers have put their attention on that field of research. So far, synthesis process involving organic compounds has been considered on waste prevention, safer solvents, design for high energy efficiency, and usage of renewable feedstocks. This review comprehensively discusses in brief about the implementation of green chemistry principle and their applications in the synthesis process of organic compounds.

“…The bands at 2924 and 2854 cm −1 assigned to the CH stretching vibrations emerged with PhBr introduced in the ethanol and water solution of Pd 1 Au 8 (Figure S6, Supporting Information). [ 27 ] The bands at 1633 and 1660 cm −1 might correspond to the adsorbed water and the signal of OH appeared at 3356 cm −1 . [ 28,29 ] In contrast, only a distinct band at 1660 cm −1 was observed with the addition of PhB(OH) 2 to the solution of Pd 1 Au 8 .…”

It has become possible to establish a connection between homogeneous and heterogeneous catalysis with atomically precise metal clusters. Due to their defined coordination geometry, in this work, atomically precise Pd1Au8(PPh3)82+ clusters are exploited to identify the crucial factor that can impact the catalytic efficiency for the Suzuki–Miyaura cross‐coupling process and further gain valuable insight into the exclusive cooperative effect of the central Pd atom and the peripheral Au atoms of the Pd1Au8(PPh3)82+ cluster on controlling the cross‐coupling reaction. Specifically, a heterogeneous catalyst, namely Pd1Au8@Resin, is designed by exchanging positively charged Pd1Au8(PPh3)82+ clusters into the porous resin, thereby not only facilitating catalyst recyclability when performed in a batch reactor, but also realizing time‐on‐stream performance for the Suzuki–Miyaura cross‐coupling reaction carried out in a fixed‐bed reactor. The integrated advantages of homogeneous complexes and heterogeneous catalysts are expected to advance the usability of atomically precise metal clusters as heterogeneous catalysts for important bond constructions in homogeneous systems.

“…In the ratio of 1:23, the yield obtained decreased because the higher the ratio of alcohol used, the higher the glycerol level produced. According to Yunnowati et al (2008), high glycerol in the methyl ester solution will encourage the reaction to turn left to form monoglycerides so that the biodiesel yield will decrease [8].…”

One of the consequences of excessive palm oil use is the production of waste palm oil (used cooking oil). To overcome this problem, efforts are needed to convert used cooking oil into more valuable products, such as biodiesel; because of its high fatty acid content, the used cooking oil has considerable potential in developing biodiesel fuel. This research aims to utilize used cooking oil in making biodiesel using heterogeneous catalyst ash derived from Nipah fruit skin calcined at 500 °C for ± 4 hours. Nipah is a type of palm (monocotyledon) that grows in mangrove forest ecosystems, in tidal areas near the seaside, or offshore. The characteristics of parts of Nipah, such as leaves, and skin, chemically contain a lot of cellulose, hemicellulose, and lignin and contain inorganic elements such as Na, K, Cl, Mg, Ca, Si, P, S, and Al. The transesterification process reacts oil with methanol to produce methyl esters and glycerol. Process variables, namely transesterification reaction time of 60, 90, 120, and 150 minutes, and the mole ratio of methanol to oil of 1:19, 1:21, and 1:23, were observed in this experiment. Biodiesel characteristics were obtained with a density of 860.2 g/mL and a viscosity of 2.37 mm2/s. They contained 44.14% Palmitic acid and 43.04% Octadecenoic acid (oleic), which is to the Indonesian National Standard (SNI). The maximum yield obtained was 93.3598% using a mole ratio of oil: methanol 1:23 at 60°C for 120 minutes, TFT 1:1, and 3% catalyst mass. The results obtained in this study indicate that Nipah fruit skin-based catalysts can be used to produce biodiesel.
