“…After that, each stem and leaves were dried in an oven at 100 o C for 4 hours, then pulverized using ball mill for 5 hours. Then the product was sieved to size of 70 mesh in order to obtain uniform powder size [5]. The powder with a composition mixture of stems and leaves 1:1 was used as raw material in furfural synthesis.…”

“…MC is known as one of the most rampant weed species in the world because of its fast-growing characteristics, surrounding other plants which can cause the plants to lack sunlight and die [4]. The main chemical composition of MC is pentosan, holocellulose, and lignin with each composition of 49.54-56.04%, 14.05±0.18%, and 23.54±0,89% [3,5]. Biomass with high pentosan content is suitable as a precursor of furfural.…”

“…The strong acid catalyst used is usually inorganic acid which can cause corrosion to the equipment and release residue which can contaminate the environment. To overcome these issues and have a more environmentally friendly process, an organic acid catalyst can be considered as an alternative [5]. The use of organic acid from bilimbi acid as catalyst in the furfural formation from MC can produce furfural yield of 7.2% [5].…”

The use of inorganic acid catalyst in furfural synthesis from biomass cause equipment corrosion and waste disposal since waste of the inorganic acid catalyst can damage environment. To overcome these issues, organic acid catalyst could be considered as an alternative. The purpose of this work was to examine the utilization of organic acid derived from tamarind as catalyst and compare it with sulfuric acid catalyst. Mikania micrantha (MC) was used as a feedstock. As much as 50 g dry MC was pulverized to 70 mesh and mixed with 50 g sodium chloride. This mixture was added into tamarind extract at ratio of 1:6 (w/v) in a three neck round bottom flask equipped with condenser, stirrer, and thermometer. The reaction was performed at 100-120 o C and for 0-330 min. Crude furfural was extracted by adding 50 ml chloroform. After extraction two layer were occurred, the bottom layer was furfural and chloroform, and the top layer was rich in water. Furfural and chloroform was separated by distillation process at 60-70C. The furfural obtained was characterized by aniline acetate reagent, density test, infrared spectrophotometer, and GC-MS. The results confirmed that organic acids from tamarind extraction can be used as a catalyst in furfural formation.

An attempt to increase the added value of lime has been done. The use of lime extract as a green catalyst in furfural manufacturing is expected to reduce the burden of pollution, and corrosion problems. This study aimed to evaluate the performance of lime extract as an organic acid catalyst in furfural production from Mikania micrantha (MM) through hydrolysis and dehydration and compare it with sulfuric acid catalyst. In this work, 50 g MM and 50 g dry NaCl powder were placed into a three neck flask equipped with a long condenser. The lime extract catalyst was added to the mixture at a ratio of 6:1 (v/w). The reaction temperature was varied from 100-120°C, and the condensed furfural was stored in an erlenmeyer as a function of time (0-330 min). Furfural was separated from water done by adding 50 ml chloroform to form two layers. The lower layer rich in furfural and chloroform was distilled at 70°C to evaporate chloroform. Purified furfural was identified using FTIR and GC-MS. The results obtained confirm that lime extract can be used as a green catalyst in furfural synthesis from MM.
