Distillation of liquid smoke is a process of heating liquid smoke based on the difference in its boiling point and then cooled to get liquid smoke with better quality. This heating aims to separate unwanted components in liquid smoke such as tar and benzopyrene. The process is strongly influenced by several things such as temperature and distillator. From these two measurements, several characteristics such as heating rate, distillation flow rate of liquid smoke, production capacity, heating temperature, steam temperature and distillation time, as well as the characteristics of the resulting liquid smoke can be known.The purpose of this study is to determine the characteristics of the 3rd grade liquid smoke distillation process with electric heating and water cooling condenser which includes the production capacity of liquid smoke and to determine the quality and quantity of liquid smoke, heating rate, electricity consumption, flow rate and to determine the efficiency of 2nd grade liquid smoke production.This research was conducted at the Laboratorium Teknik Mesin Universitas Muhammadiyah Metro, this study used a distillation apparatus made of Aluminium plate 1 mm thick, 180 mm in diameter, 250 mm high. Condenser with 0.5 inch diameter copper pipe 3,5 m long, 3 inch diameter PVC pipe, 3m long. The raw material for 3rd grade liquid smoke is 3 liters.The results obtained that the distillation apparatus has a capacity of 3 liters, the distillation temperature affects the rate of heating that occurs, namely the distillation temperature of 110oC, the heating rate is 707,42 J/second, the electricity consumption is 4,48kWh, the time is 45 minutes, and for a temperature of 120 oC the heating rate is 754,60 J/second, electricity consumption is 4,467 kWh in 65 minutes. The highest yield of liquid smoke is at a temperature of 110 oC, which is 2840 ml with a flow rate of 8,35 ml/minute and an efficiency of 94,6%, pH level of 2,15. And for a temperature of 120 oC it produces 2560 ml of liquid smoke, with a flow rate of 8,67 ml/minute and an efficiency of 85,3%, with a pH level of 2,10.

Glycerol as a byproduct of biodiesel production was approximately formed 10% of the biodiesel weight. Impurities which contained in the glycerol such as catalyst, soap, methanol, water, salt, and matter organic non glycerol (MONG) have a significant effect on the glycerol concentration. So, it is necessary to treat the impurities. The purpose of this study is to know the effect of chloroform to glycerol purification process with acidification method using hydrochloric acid as pretreatment process. This research was begun with acid addition to the glycerol to neutralize the base content and to split the soap content into free fatty acid and salt, that are more easily separated from glycerol. Then the process was continued with extraction by the solvent chloroform using the variable of test volume ratio (v/v) (1:1, 1:1.5, 1:2)  and the extraction time (20, 40, and 60 minutes). The results showed that the more volume of solvent used, gave less extraction time to produce high purity of glycerol. The highest purity produced in this study amounted to 90,9082% is obtained at the ratio of the volume solvent (v/v) 1:1 with extraction time 60 minutes.

Palm shell liquid smoke obtained by pyrolysis and redestilasi still produce a pungent smoke flavor and color of yellow to brownish yellow so that the necessary research purification of smoke that can be used as ingredients other than preservatives, such as antiseptic hand wash. The research objective is to reduce the stinging liquid smoke aroma, color is tawny and to identify the characterization of the active components of liquid smoke shell oil refining results in Gas Chromatography Mass Spectrometry (GC-MS). The purification process of liquid smoke with redistilled at a temperature of 2000C and by adding 4.5% zeolite adsorbent made three (3) times the resulting liquid smoke of distillate and residue. Liquid smoke produced from distillate and residue are added activated charcoal as much as 9%, 10.5% and 12%, then stirred with a shaker subsequently allowed to stand for 6 days and 10 days The results of the study showed that liquid smoke purification results of the residue by the addition of activated charcoal as 12% and the time saved for 10 days (A2B2C3) gives flavor and color by 1.94 of 1.84 is odorless, yellowish white color and clarity. While the characteristics of the active components of purification results are predominantly acetic acid and phenol compounds of residues that serve as preservatives, antibacterial and antioxidant compounds while PAH (Polycyclic Aromatic Hydrocarbon), namely tar, benzoperen, gualakol and siringoll (aroma causes) undetectedABSTRAKAsap cair cangkang sawit yang diperoleh melalui proses pirolisis dan redestilasi masih menghasilkan aroma asap menyengat dan warna kuning hingga kuning kecoklatan sehingga diperlukan penelitian pemurnian asap yang dapat digunakan sebagai bahan lain selain pengawet, seperti antiseptik pencuci tangan.

With regard to the importance of quinazoline as a privileged scaffold, herein we report the synthesis of twenty seven 2,4-disubstitute quinazoline derivatives in a new catalyst free condition. In the current work, poly ethylene glycol (PEG1000) as an inexpensive, very simple commercially available, ecofriendly and low melting point solvent was used. Air bubbling, a green oxidant, for oxidation purpose was also used. This is the first report about using PEG1000 as a solvent simultaneously with air bubbling as oxidant in quinazoline synthesis. All of the compounds 1-27 were synthesized in high yield with very simple work up and purification process without using column chromatography. All the structures were confirmed using 1H NMR, 13C NMR, IR, MS and elemental analysis.

Abstract Objectives The purpose of this study is to analyze the effects of rice husk liquid smoke in Porphyromonas gingivalis-induced periodontitis in the inflammatory and proliferation marker such as nuclear factor kappa β (NF-kB), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), transforming growth factor-β (TGF-β), fibroblast growth factor 2 (FGF2), collagen type 1 (COL-1) expression, and the number of macrophages, lymphocytes, and fibroblasts. Materials and Methods Rice husk liquid smoke is obtained by the pyrolysis process. Porphyromonas gingivalis-induced periodontitis in 20 μL phosphate-buffered saline containing 1 × 109 CFU was injected into the lower anterior gingival sulcus of Wistar rats. The periodontitis was then treated with 20 μL/20 g body weight of rice husk liquid smoke once a day for 2 and 7 days, respectively. After treatment, the bone and lower anterior gingival sulcus were analyzed with immunohistochemistry and hematoxylin–eosin staining. Results The treatment of periodontitis with rice husk liquid smoke showed a lower NF-kB, TNF-α, and IL-6 expression and a higher TGF-β, FGF2, and COL-1 expression than the control after treatment for 2 and 7 days (p < 0.05), respectively. The number of macrophages and fibroblasts was also higher when compared with the control group (p < 0.05), but the number of lymphocytes was lower than the control (p < 0.05). Conclusion Rice husk liquid smoke showed its effects on Porphyromonas gingivalis-induced periodontitis with a decrease in inflammatory markers and an increase in proliferation markers. The development of a rice husk liquid smoke periodontitis treatment is promising.
