The invention relates to a method for producing alcohols by homogeneously catalysed hydroformylation of olefins to aldehydes and subsequent hydration of the aldehydes. The invention further relates to a system for carrying out the method. The main focus is on the separation technique for work-up of the hydroformylation mixture. The problem addressed by the invention is that specifying a work-up method for hydroformylation mixtures that utilises the specific advantages of known separation technologies but at the same time largely avoids the specific disadvantages of said separation technologies. The most important objective is to create a catalyst separation system that is as complete and at the same time conservative as possible and that operates in a technically reliable manner and entails low investment and operating costs. The method should be unrestrictedly suitable for processing the reaction output from oxo systems in “world scale” format. The problem is solved by combining membrane separation units and a thermal separation unit, the thermal separation unit being operated in such a manner that 80% to 98% of the mass introduced with the product stream into the thermal separation unit exits the thermal separation unit again as a head product. 1.

A method of producing 1,5-pentanedial having an alkyl group at the 3-position, including a step of hydroformylating an aldehyde compound represented by the following general formula (1): 2. The production method according to claim 1 , wherein the hydroformylating step is performed in the presence of a Groups 8 to 10 metal compound and a ligand.3. The production method according to claim 2 , wherein the Groups 8 to 10 metal compound is a rhodium compound. The present invention relates to a method of producing a dialdehyde compound. Specifically, the present invention relates to a method of producing 1,5-pentanedial having an alkyl group at the 3-position.Various compounds have been known as 1,5-pentanedial having an alkyl group at the 3-position. For example, 3-methylglutaraldehyde (3-methyl-1,5-pentanedial, which is hereinafter abbreviated as MGL) is a compound that is useful as a curing agent for a photosensitive material, a leather tanning agent, and a synthetic intermediate (see, for example, PTLs 1 to 3). The known production methods of MGL include a method of hydrolyzing pyranyl ether obtained through Diels-Alder reaction of crotonaldehyde and methyl vinyl ether (see NPLs 1 and 2).The aforementioned ordinary method has room for improvement since the Diels-Alder reaction of crotonaldehyde and methyl vinyl ether has low reactivity and requires severe conditions including a high temperature and a high pressure, the productivity thereof is insufficient due to the prolonged reaction time, and the yield of MGL is low. Accordingly, an object of the present invention is to provide a method of producing 1,5-pentanedial having an alkyl group at the 3-position, such as MGL, under mild conditions with a good yield.The present invention relates to the following items [1] to [4].[1] A method of producing a dialdehyde compound represented by the following general formula (2) (which is hereinafter referred to as a dialdehyde compound (2)):wherein Rrepresents an alkyl group ...

A process for continuous, on-demand production of dilute acrolein liquid on-site, at or near the point of acrolein injection, by the liquid dehydration of glycerol in an improved tubular reactor where non-aqueous glycerol is combined with a heteropolyacid catalyst, including silicotungstic acid, phosphotungstic acid, or phosphomolybdic acid. The acid catalyst is evenly dissolved and dispersed in the glycerol upstream of the reactor vessel. The reaction is conducted in a tubular reactor which is heated to an elevated reaction temperature. The dilute acrolein produced in the tubular reactor is directed downstream, optionally through a liquid-liquid heat exchanger and then an air-liquid heat exchanger to reduce temperature, and then diluted prior to being injected into sulfide contaminated systems (such as oil & gas water floods, water disposal systems, producing oil wells, and fuel oil storage) via a pressure conduit.
