摘要:A method of the invention industrially produces heterocyclic mercapto compounds useful as raw materials or intermediates in the synthesis of medicaments or pesticides, or as permanent wave agent, with a high yield and high productivity using easily available starting materials. A heterocyclic mercapto compound represented by Formula (1) (wherein X represents any structure of —O—, —S—, —NH—, and —NR 1 —; R 1 represents any of an alkyl group, alkoxy group and alkoxyalkyl group each having 1 to 6 carbon atoms; Y represents an oxygen atom, a sulfur atom or —NR 2 —; R 2 represents a hydrogen atom or alkyl group having 1 to 6 carbon atoms; and Z 1 represents a divalent organic residue having at least one mercapto group) is produced by reacting a metal sulfide or a metal hydrosulfide with a compound represented by Formula (2) (wherein X and Y are as defined in Formula (1); and Z 2 represents a divalent organic residue having at least one halogen group) in the presence of a solvent at a pH of 7.0 to 11.0.

摘要:Techniques and mechanisms for synthesizing quantum dot structures. In an embodiment, a first reaction is performed to dissolve a precursor of a semiconductor material, wherein water is created as a by-product of the first reaction. Some or all of the water is removed and another chemical compound is added, wherein the chemical compound is a primary alcohol or a 1,2-diol. After the addition of the chemical compound, a second reaction is performed to grow at least some nanocrystalline portion of the quantum dot. In another embodiment, the chemical compound is 1,2-hexanediol, 1,2-dodecanediol or 1-octadecanol.

摘要:The present invention provides a method for simplifying manufacture of a mixed alcohol or mixed oxygenate product from synthesis gas. The mixed alcohol or mixed oxygenate product contains ethanol and other oxygenates with two or more carbon atoms per molecule. The method includes stripping a portion of carbon dioxide and inert gases contained in a mixed alcohol synthesis reaction product using a methanol-containing stream, such as one produced as part of the method, as a medium to absorb said carbon dioxide and inert gases and recycling light products and heavy products to one or more of synthesis gas generation, mixed alcohol synthesis and separation of desired mixed alcohol or mixed oxygenate products from other components of a mixed alcohol synthesis stream. The present invention also provides downstream processing of the mixed alcohol or mixed oxygenate product by subjecting the product to a dehydration step in order to convert at least ethanol, preferably at least ethanol and propanol, to their corresponding olefins (e.g. ethylene and propylene).

摘要:The present invention relates to a process for preparing synthesis gas and at least one organic, liquid or liquefiable value product, by a) providing a biomass starting material, b) subjecting the biomass starting material to digestion, c) optionally, from the digested material obtained in step b), isolating at least one fraction C1) with a heightened aromatics content and at least one fraction C2) with a lowered aromatics content, d) feeding the digestion product from step b) or the high-aromatics fraction C1) from step c) into a dealkylating zone and reacting it in the presence of hydrogen and/or steam, e) taking a discharge from the dealkylating zone and subjecting it to separation, to produce at least one organic, liquid or liquefiable value product and at least one stream with a heightened content of volatile components lighter than the organic value product, and f) using the stream obtained in step e), with a heightened content of volatile components lighter than the organic value product, at least partially for preparing synthesis gas.
