Methyl Methacrylate By Lucite's
Alpha Technology (January 2003)
http://pep.sric.sri.com/Public/Reports/Phase_99/RW99-14/RW99-14.html
Lucite (formerly Ineos Acrylics) and Kvaerner have developed a new technology, Alpha, to produce methyl methacrylate (MMA) from ethylene in two reaction steps. The process is claimed to avoid the environmental problems of the conventional acetonecyanohydrin route, which involve handling highly toxic hydrogen cyanide and disposing of large amounts of ammonium bisulfate by-product. In addition, the Alpha technology uses only commodity feedstocks-ethylene is reacted with methanol and carbon monoxide to form methyl propionate, which is then reacted with formaldehyde to yield MMA and water.
Lucite
http://www.luciteinternational.com/aboutus_values_rte.cfmWe have developed a fully patented new low cost route for the production of MMA - known as Alpha. This is being successfully piloted ahead of the first full-scale plant in the USA. The Alpha process uses ethylene and methyl-propionate in a two-stage process to manufacture MMA and is ideal for world scale production (more than 100 kte/220 mm lbs per annum). An alternative route to this process, known as Beta, produces MMA competitively on a smaller scale (40 - 50 kte/88 - 110 mm lbs a year) - through the conversion of methyl-propadiene in a single-stage process. In addition, the company has developed a new, highly competitive route to hydrocyanic acid. Known as Omega, this process is currently in operation at a full-scale pilot facility in Cassel, UK. Each of the three technologies has been patented.
アクリル板を溶かすと柔らかスポンジに 阪大教授が発見
透明なアクリル板を、アルコールと水の混合液に漬けて温めると、柔らかなスポンジに――大阪大の宇山浩教授（応用化学）が、こんな発見をした。このスポンジには微小な穴があり、ナノテクノロジー（超微細技術）の材料になるという。医療や化粧品などへの応用が期待される。
スポンジを調べると、約３００ナノメートル（ナノは１０億分の１）の粒子が連なったナノ多孔体といわれる状態になっており、弾力が生じていた。
