Kebony
Kebony is a Norwegian wood producer. The company has its roots in Wood Polymer Technologies (WPT), which was founded in 1996 and changed its name to Kebony in 2007. Kebony has a factory in Skien (Norway) and offices in Oslo (Norway). Technology Kebony has developed an environmental technology which provides an alternative to threatened and endangered tropical hardwoods, and traditional impregnated wood. In the process, a liquid byproduct of the sugar industry, furfuryl alcohol, is used to treat the wood. Using pressure, vacuum and heat treatment, the liquid transforms to furan resin Furan resin refers to polymers produced from various furan compounds, of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation. Th ... and is tied together with the cell structure of the wood in order to improve the wood's abilities permanently. The woods used are FSC-certified, PEFC ...

Furfuryl Alcohol
Furfuryl alcohol is an organic compound containing a furan substituted with a hydroxymethyl group. It is a colorless liquid, but aged samples appear amber. It possesses a faint odor of burning and a bitter taste. It is miscible with but unstable in water. It is soluble in common organic solvents. Synthesis Furfuryl alcohol is manufactured industrially by hydrogenation of furfural, which is itself typically produced from waste bio-mass such as corncobs or sugar cane bagasse. As such furfuryl alcohol may be considered a green chemical. One-pot systems have been investigated to produce furfuryl alcohol directly from xylose using solid acid catalysts. Reactions It undergoes many reactions including Diels-Alder additions to electrophilic alkenes and alkynes. Hydroxymethylation gives 1,5-bis(hydroxymethyl)furan. Hydrolysis gives levulinic acid. Upon treatment with acids, heat and/or catalysts, furfuryl alcohol can be made to polymerize into a resin, poly(furfuryl alcohol). Hydrog ...

Furan Resin
Furan resin refers to polymers produced from various furan compounds, of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation. The resins are generally used as binders for sand castings. The furan monomer is typically converted to a free-flowing resin with mild acid catalysis. Curing is achieved using strong acid. Types The term furan resins is not used uniformly in the literature. For example, some authors refer to resins based on furfuryl alcohol and furan as furan resins, while othersMichael Biron: '' Thermosets and composites : material selection, applications, manufacturing, and cost analysis.'' Elsevier, Amsterdam, 2014, , S. 257–259. use the term only for resins based on furfuryl alcohol. In addition to homopolymers of the two starting materials, also copolymers comprising for example methanal, urea or phenol are counted as furan resins.Arne Gardziella ...

Oslo
Oslo ( , , or ; sma, Oslove) is the capital and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of in 2019, and the metropolitan area had an estimated population of in 2021. During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a ''kaupstad'' or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality ('' formannskapsdistrikt'') on 1 January 1838. The city fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skien, Norway
Skien () is a city and municipality in Vestfold og Telemark county in Norway. In modern times it is regarded as part of the traditional region of Grenland, although historically it belonged to Grenmar/Skiensfjorden, while Grenland referred the Norsjø area and Bø. The administrative centre of the municipality is the city of Skien. Skien is also the capital of Vestfold og Telemark county. Skien is one of Norway's oldest cities, with an urban history dating back to the Middle Ages, and received privileges as a market town in 1358. From the 15th century, the city was governed by a 12-member council. The modern municipality of Skien was established on 1 January 1838 (see formannskapsdistrikt). The rural municipalities of Gjerpen and Solum were merged into the municipality of Skien on 1 January 1964.
