The present invention is to provide compositions comprising organic compounds useful as a chemical industrial material or a fuel composition with the use of an alcohol such as ethanol as a material. It is a method for producing compositions using alcohol as a starting material and comprising: allowing alcohol to contact with an alcohol conversion catalyst such as hydroxyapatite (first step) and conducting a hydrogenation reaction respectively for all reaction products consisting of a liquid phase including alcohols, water and hydrocarbons of 4-12 carbons and a gas phase which is light gas containing paraffins, alcohols and olefins; all liquid phase reaction products consisting of all reaction products from which light gas has been removed; a liquid phase dehydration reaction products consisting of all reaction products from which light gas, unreacted alcohol and product water have been removed; and light gas (second step).

The invention discloses a preparation method of multi-taste Maotai-flavor white spirit. Eleven flavor types of white spirits are taken as seasoning liquors, the preparation method is characterized by comprising the following steps of: finishing and soaking grains; cooking, gelatinizing and mixing with Luzhou-flavor white spirit fermented grains and Maotai-flavor white spirit fermented grains; spreading out and airing, stirring distiller's yeast, adding Maotai-flavor ending liquor, Luzhou-flavor yellow wine, Maotai-flavor fermented grains and Maotai-flavor yeast, and accumulating and fermenting; fermenting in a cellar, and spraying mixed solution of the Maotai-flavor ending liquor and the Luzhou-flavor yellow wine on the surface of each distilled grain layer; making sand and adding the Luzhou-flavor white spirit fermented grains, cooking and gelatinizing, then adding the Maotai-flavor ending liquor, the Luzhou-flavor yellow wine, the Maotai-flavor fermented grains and the Maotai-flavoryeast, accumulating and fermenting, and storing in the cellar and spraying the mixed solution of the Maotai-flavor ending liquor and the Luzhou-flavor yellow wine on each distilled grain layer; steaming by using a rice steamer to obtain unblended wine in rounds of 1, 2, 3, 4, 5, 6 and 7, and the wine in the seven rounds are combined according to taste and-flavor characteristics, so as to obtain combined Maotai-flavor unblended wine; and then blending the combined unblended wine with flavoring liquor, thus obtaining the multi-taste Maotai-flavor white spirit. The preparation method disclosed by the invention has the advantages of enriching-flavor of Maotai-flavor white spirit, meeting market demand and promoting development of the Maotai-flavor white spirit.

The invention discloses a preparation process of formaldehyde-free plywood, including veneer manufacturing, glue mixing, sizing, billet formation, cold pressing, and post-processing. After the cold pressing process, a hot pressing process is required. In the sizing process, the water-based polyurethane mixture is used as the adhesive. The invention is suitable for using the water-based polyurethane, and realizes the preparation process of the plywood plywood with good bonding strength, uniform thickness of the slab, not easily deformed, and good stability.

The invention discloses a method of treating waste water including hydroxybenzene, including following steps: (1) synchronously adopting three segments target control method, a control method of mol ratio of hydroxybenzene to aldehyde and a timely separating method of resin and waste water, and processing a condensation polymerization of waste water in an acid condition with acid catalyst to produce resin with low molecular weight; (2) removing aldehyde of the waste water after the first treatment in an alkaline condition with alkaline catalyst and then processing an neutralization and deposition treatment; (3) adopting anaerobic and aerobic treatment to process a biochemical treatment of the waste water after the second treatment to meet emission requirements. The method meets the prescribed emission requirements of the hydroxybenzene-aldehyde resin waste water or waste water containing hydroxybenzen and has a simple art, a reliable operation, a low investment and a low operation fees and adequately utilizes the hydroxybenzene-aldehyde in the waste water.

The invention discloses a method for extracting litsea cubeba oil. The whole fresh fruit of litsea cubeba is added in a boiling state, the steam pressure is 0.2-0.3MPa, and the water is distilled for 1-1.5h, the oil and water are separated to obtain litsea cubeba oil, and the liquid residue is separated , drying the combined seed cores to obtain dry litsea cubeba seed cores, and adding strains to the fruit puree to produce bio-organic fertilizers according to the usual method. Compared with the existing crushing or peeling technology, the present invention reduces the equipment investment for fresh fruit crushing or peeling, prevents litsea cubeba pulp from contacting with air, improves the oil yield and product quality, and the oil yield is 5.5-5.8%. The total aldehyde content reaches more than 75%. The by-product dried cubeb seeds are used as medicinal materials and food, and bio-organic fertilizers are used for forestry and agriculture, realizing resource recycling economy, shortening the production cycle, high equipment utilization rate, large processing capacity, energy saving and reduction consumption, reduces production costs, and has good economic, social and ecological benefits. Patents have good economic, social and ecological benefits.
