41 results about "Coniferyl alcohol" patented technology

Coniferyl alcohol is an organic compound. This colourless crystalline solid is a phytochemical, one of the monolignols. It is synthesized via the phenylpropanoid biochemical pathway. When copolymerized with related aromatic compounds, coniferyl alcohol forms lignin or lignans. Coniferin is a glucoside of coniferyl alcohol.

Fabricating method of formaldehyde-free wheat straw medium density fiberboard

The invention relates to a fabricating method of a formaldehyde-free wheat straw medium density fiberboard, which comprises the following steps: wheat straw chemical-mechanical pulp is added with NaAc-HAc buffer to dilute pulp into wheat straw fiber suspension with mass concentration of 2-10%; coniferol-beta-D-glucoside that is 1-10% of oven dry wheat straw pulp, 0.05-0.5% of beta-glucosidase with concentration of 6.3u / mg, 1-12% of pectin colloid and 1-8% of cationic paraffin emulsion are respectively added in the suspension; and then, 10U / g-80U / g of laccase is added in the suspension to start reaction; the processed wheat straw fiber is scattered through an electric mixer; a fiberboard former is used to shape the fiberboard; excess water is removed by prepressing; and at last the fiberboard is obtained by hot pressing. By virtue of the fabricating method, the physical mechanical property and water-resistant performance of the wheat straw medium intensity fiberboard are improved; the pollution problem of free formaldehyde generated during the process of artificial board production and utilization is solved; waste materials such as crop wheat straw can be utilized; and the environment pollution is reduced.
