“…The removal of water produced during reaction in time was the research topics in recent years. The alternative route of one-pot reaction from CO 2 and ethanol in the presence of epoxide as a dehydration agent was reported to enhance the DEC yield [16,17]. Nevertheless, the raw materials of epoxides were relatively expensive.…”

“…The mechanisms of the reaction have been studied and proven by many researchers [21,23]. As analyzed by the GC-MS method in this work, the main products in the one-pot reaction from CO2, ethanol and PO were 1,2-propanediol (PG), DEC and propylene carbonate (PC) with the side-product 1-ethoxy-2-propanol (EP).…”

“…In addition, the one-pot synthesis of DEC from carbon dioxide, ethylene oxide (EO) and ethanol on the KI and sodium ethoxide binary homogeneous catalyst was also researched by Wang et al [21], and the yield of DEC was improved. However, KI and sodium ethoxide are dissolved in ethanol and cannot be separated easily.…”

Abstract:One-pot syntheses of diethyl carbonate (DEC) from CO 2 , propylene oxide and ethanol were carried out using different solid catalysts. The supercritical CO 2 extraction method was used to separate the liquid products and reactants from the catalysts after reaction. The KNO 3 -CeO 2 and KBr-KNO 3 -CeO 2 were found to be active for the reaction after calcinations. The catalyst was also reusable. The thermodynamic properties of the reaction were also evaluated. The effects of various conditions, such as reaction time, amount of catalysts, molar ratio of the reactants, the composition and calcination temperature of the catalysts on the conversion and yields, were investigated, and the yield of DEC was about 13.0% with a selectivity of 38.5% over KBr-KNO 3 -CeO 2 . The yield of DEC was improved about 10-fold by using KBr-KNO 3 -CeO 2 catalyst compared to CeO 2 .

“…Kajian studi pra desain pabrik untuk sintesa DEC dari CO 2 sebelumnya mencoba menggunakan indirect route dengan katalis CeO 2 , akan tetapi memiliki yield reaksi yang lebih kecil [4]. Studi terakhir menunjukan bahwa hasil terbaik yang tercapai berupa : 63,6% dari yield DEC dan 68,5% dari yield glikol (produk samping) dimana 97,5% konversi Ethylene oxide (EO) bisa tercapai pada 443 K dan 3 MPa CO2 tekanan awal dalam waktu operasi 3 jam [5].…”

Abstrak-Konsumsi bahan bakar minyak yang terus meningkat menyebabkan polusi CO 2 . Eksplorasi dan pemanfaatan gas alam, seperti pada Natuan Gas field, akan menghasilkan banyak emisi CO 2 . Pada penelitian ini telah dilakukan perancangan pabrik Dietil Karbonat dengan bahan baku CO 2 dimana kapasitas produk DEC sebesar 10.565.449 ton/tahun dan sales gas sebesar 45.299.932 MMBtu/tahun, dengan umur pabrik 20 tahun yang berjalan kontinyu selama 330 hari / tahun. Tujuan perancangan pabrik dietil karbonat adalah untuk memanfaatkan CO 2 dari hasil gas alam pada Natuna gas field. Pabrik dietil karbonat direncanakan didirkan pada Kepulauan Natuna, Provinsi Kepulauan Riau. Tempat ini dipilih karena tersedia akses terhadap bahan baku utama berupa gas alam pada perairan Natuna, sarana transportasi darat dan laut, ketersediaan listrik, air dan pemasaran produk dapat dilakukan pada daerah Balikpapan, dan luar negeri melalui Singapura. Pada pabrik ini digunakan proses direct synthesis menggunakan bahan baku CO 2 , etanol, dan etilen oksida dimana katalis KI dan sodium etoksida digunakan dalam proses sintesa. Produk samping dari proses ini ialah etilen karbonat (4.319.760 ton/tahun), etilen gilkol (5.501.320 ton / tahun) dan cellosolve (846.776,7 ton/tahun) yang memiliki nilai jual yang baik. Secara analisis ekonomi didapatkan total investment cost : 25.047,69 Juta USD, net pressent value : 148,121 juta USD, IRR : 35,84%, dan POT : 3,611 tahun sehingga pabrik pemanfaatan gas alam pada Natuna gas field perlu dipertimbangkan
