The present disclosure provides methods to produce 5-(halomethyl)furfural, including 5- (chloromethyl)furfural, by acid-catalyzed conversion of C6 saccharides, including isomers thereof, polymers thereof, and certain derivatives thereof. The methods make use of acids with lower concentrations, and allows for conversion of sugars into 5-(halomethyl)furfural at higher temperatures and faster reaction or residence times.

A process is disclosed for making dehydration products from an aqueous sugars solution including pentoses, hexoses or both, for example, an aqeous high fructose corn syrup solution, or from an aqueous solution of one or more of the alcohols of such pentoses and hexoses, for example, from an aqueous sorbitol solution, by an acid-catalyzed dehydration using substituted sulfonic acids solubilized in the aqueous sugars or sugar alcohols solution.

A fructoside-containing product is manufactured from a glucose-rich feedstock, in a process wherein glucose to fructose is isomerized by contacting the glucose-rich feedstock with a basic isomerization catalyst in an alcoholic medium at a temperature of at least 75 °C, to yield a fructose-containing product; and wherein at least part of the fructose-containing product obtained therefrom is reacted with an alcohol in the presence of an acid catalyst to yield a fructoside-containing product.
Provided is a two-step method of producing a compound of chemical formula 1 in the presence of an alcohol solvent and a Group 3B metal catalyst or a salt thereof, comprising a first step comprising alkylation or isomerization of an aldohexose-containing substrate to obtain an intermediate, and a second step comprising dehydration of the intermediate to produce a compound of chemical formula 1. Preferably, additional solvent and/or catalyst are not added in the second step.

Accordingly, the current invention provides a method for the manufacture of a mixture of a furfural and a 5-(alkoxymethyl)furfural derivative by reacting a C5 and C6 sugar- containing starting material with an alcohol in the presence of an acid catalyst, followed by the hydrogenation and/or etherification of the mixture of furfural and 5-(alkoxymethyl)furfural to convert the aldehyde function of both 5-(alkoxymethyl)furfural and furfural into an alkoxymethyl function or methyl function.
