Problems solved by technology
[0005] The present invention aims at the low reaction conversion rate and many by-products in the chlorination stage of the existing methyl / ethyl maltol production, and the existing maltol pipeline chlorination reaction method simply prolongs the passing time of the reactants so that the reaction materials can fully contact The problem that the effect is not ideal provides a method of shortening the reaction time, effectively reducing the side reaction of the chlorination reaction in the production of methyl / ethyl maltol, and improving the conversion rate of the chlorination reaction in the production of methyl / ethyl maltol Methyl / ethyl maltol chlorination section production equipment

The invention claims protection of a methyl / ethyl maltol chlorination section production equipment, which is characterized in that it includes a first pipeline reactor and a second pipeline reactor arranged in series, and a mixed-flow reactor is sequentially arranged inside the first pipeline reactor device and turbulent flow device, a turbulent flow device is set inside the second pipe reactor, a chlorine pipe is provided on the first pipe reactor near the feed inlet, and a chlorine pipe is arranged on the second pipe reactor near the feed inlet. The chlorine supplement pipe, through the mixed flow plate and the turbulence device, makes the material in the inner tube of the pipeline reactor in a turbulent state, the contact surface between the materials is constantly updated, and the gas-liquid mixing is strengthened, which effectively improves the efficiency of the chlorination reaction and reduces the chlorination reaction Side reactions, thereby increasing the yield of maltol / ethyl maltol.
Description
technical field [0001] The invention relates to the technical field of flavor essence production, in particular to a methyl / ethyl maltol chlorination section production equipment. Background technique [0002] Maltol, also known as methyl maltol, is a white needle-like crystal or white crystalline powder with a melting point of 162-164°C. It is a natural compound that emits aroma and is widely found in foods such as soybeans, coffee, bread and caramel. Ethyl maltol, white needle-like crystal or white crystalline powder, melting point 89-93°C, has a long-lasting caramel and fruity aroma, and the dilute solution has a sweeter fruity aroma. Ethyl maltol is a homologue of maltol. Due to the slight change in molecular structure, its aroma is stronger and more volatile. It is a good aroma enhancer for tobacco, food, beverage, essence, fruit wine, daily cosmetics, etc. Efficacy agent, which has a significant effect on improving and enhancing the flavor of food, sweetens sweets, an...
