What is Methyl Maltol?

Ethanolamine EA is the most essential item among amino alcohols, including monoethanolamine MEA, Diethanolamine SigmaDEA as well as triethanolamine TEA. Ethanolamine is an important organic intermediate, extensively utilized in surfactants, artificial detergents, petroleum additives, artificial resins as well as rubber plasticizers, accelerators, vulcanizing agents and lathering representatives, along with gas filtration, liquid antifreeze, Printing as well as dyeing, medication, pesticide, building and construction, army and also various other areas. Many downstream items of ethanolamine are essential great chemical intermediates, and also they are additionally one of the most sought-after chemical items in our nation. Consequently, the application and also growth of ethanolamine has been enhanced to meet the requirements of domestic great chemicals on the one hand, as well as advertise the quick growth of the ethanolamine market on the other hand.

Diethanolamine Sigma, additionally referred to as bishydroxyethylamine, 2,2′-iminobisethanol, is a white crystal or anemic liquid with solid hygroscopicity. It is easily soluble in water, methanol, ethanol, acetone and also benzene, as well as its solubility in benzene (g/100g) at 25 ° C is 4.2 as well as 0.8 in ether. Its usages are: gas detoxifying agent, which can soak up acid gases in the gas, such as carbon dioxide, hydrogen sulfide, sulfur dioxide, and so on. The “Benfield” option used in the artificial ammonia market is generally made up of this item; it is additionally utilized as an emulsifier., lubricating substances, shampoos, thickeners, etc; natural synthesis intermediates for the production of detergent resources, preservatives and day-to-day chemicals (such as surfactants); synthesis of morpholine.

Methyl Maltol Uses

  1. Methyl maltol is commonly used in the formulation of everyday needs significance, yet the dosage is incredibly low. For ache needles as well as roses, it has cozy as well as pleasant result.

  2. Methyl maltol is an edible flavor that is enabled to be used according to GB 2760-1996. It is mostly utilized to prepare strawberry, coffee, malt, nuts, vanilla and different fruit tastes. For bread, cakes have a newly baked taste.
  3. Methyl maltol, namely maltol, is a food seasoning enabled to be utilized in my nation’s “Hygienic Specifications for using Food Additives”. It is mainly used in cakes, chocolates, candies, tobacco and alcohol flavors, and also acts as a sugar and also flavor synergist. 90mg/kg in eating gum tissue; 31mg/kg in candy; 30mg/kg in baked items; 15mg/kg in jelly; 8.7 mg/kg in cold drinks; 7.5 mg/kg in desserts; 4.1 mg/kg in sodas.
  4. Methyl maltol has sugar aroma and strawberry scent in weaken solution. Maltol is a derivative of γ-pyrone, generally used as food flavor enhancer, everyday requirements and tobacco taste, photosensitive product, preservative and also skin treatment medication. Including a small amount of maltol to food not only enhances and also increases the fragrance, however also prolongs the storage duration of the food without mold. It is used to make the significance of everyday necessities, and it can additionally put in an excellent fragrance effect.

It has an exceptional impact on boosting and enhancing the flavor of food, as well as has a sweetening result on desserts. One component maltol can be used instead of four parts coumarin. Adding 5-200g of maltol per ton of feed can advertise the quick development of hogs.

Methyl Maltol Purification

A method for decolorizing and recrystallizing methyl maltol, comprising the following steps:

(1). First put 500L of alcohol into the roughing kettle and stir, then put 800kg of the crude product frozen by chlorination and hydrolysis into the roughing kettle and heat it to 60℃~70℃ to dissolve it completely.

(2). After the crude product is dissolved, pump it into the first decolorization kettle, throw 50kg of activated carbon, control the temperature at 60°C-70°C and stir for 1 hour, then put it into the filter for filtration, and then send it to the second decolorization kettle with a circulating pump. The filtered activated carbon is collected and sent to the designated solid waste treatment plant for treatment.

(3). Throw 20kg of activated carbon into the second decolorization kettle, and control the temperature at 60°C to 70°C for secondary decolorization (the filtered solution is a colorless and transparent liquid), put it into the filter and send it to the freezer for freezing with a circulating pump after half an hour , The filtered activated carbon is collected and sent to the designated solid waste treatment plant for treatment.

(4). When the temperature of the kettle is frozen below 5°C, put it into a centrifuge to dry it, and obtain the desired product methyl maltol wet product (white crystal), and then send it to a drying room to dry into a finished product package. The centrifuged liquid is collected and distilled to recover alcohol. The yield is above 95%.

The Production Method of Methyl Maltol

There are three primary methods of making maltol
1. Extraction from natural items Maltol exists in the decay liquid of wheat and soybean and the roasting condensate of barley, as well as also exists in the bark of some fir trees as well as larch trees. In 1986, the United States made use of the removal condensation approach to essence maltol from timber vinegar. In 1970, the United States removed maltol from larch bark with chloroform. In Japan, it is straight drawn out from the leaves of cercidiphyllum japonicum with chloroform or drawn out from its heavy steam distillate. Maltol can additionally be divided from timber tar acquired by dry distillation of wood under decreased stress.
2. Semi-synthetic method (utilizing kojic acid as resources) The moms and dad of koji acid (Kojicacid) is sugar, which is equivalent to the dehydration item of 3-keto-glucose. The starch is fermented with Aspergillus flavus, and also the kojic acid generated in the fermentation broth is exchanged kojic acid, oxidized with air (or oxygen) under the catalysis to sulphuric acid, and afterwards decarboxylated at 225 ° C to pyromeiconic acid. Under alkaline problems, pyromeiconic acid is reacted with formaldehyde to produce hydroxymaltol. Then make use of hydrochloric acid and zinc powder to reduce maltol. After purification or sublimation and recrystallization in chloroform, the finished item of maltol can be obtained. Kojic acid can be made from kojic acid, and kojic acid benzyl ether can additionally be generated by etherification of kojic acid and benzyl chloride, and after that oxidized with manganese dioxide to create kojic acid ether, and afterwards debenzylated to develop kojic acid.
3. Manufacture maltol with furfural as raw material.
