A Prep job method of Triglycerol Monostearate is to use glycerol as basic material:
The particular prep job actions are as stick to:
( 1) Glycerol polymerization: Using alkali as a motorist, glycerol is pressed and dried out under nitrogen protection at around 260 ° C to produce tripolyglycerol.
( 2) Alcoholization of tripolyglycerol: Using antacids as a vehicle driver, tripolyglycerol and stearic acid are straight esterified at around 230 ° C under nitrogen protection.
During this preparation job treatment, moisture will be created that make up around 4% of the complete amount of materials (that is, the complete thing output will certainly be lowered by around 4%). The moisture requires power to be eliminated (currently removed throughout the chemical reaction procedure). Furthermore, stearic acid is fairly pricey, thus raising production rates. Some manufacturers additionally make use of set oil and tripolyglycerol as raw materials to prepare tripolyglycerol monostearate, however they still can not resolve the issue of high price.
Information Prep Job Approach:
( 1) Under a pressure of -0.09 MPa, mix glycerol and a compound blended alkaline motorist (a mixture of NaOH and NaH2PO2 with a mass proportion of 1:1) bookkeeping for 0.4% of the weight of glycerin and warm it to 250 ° C. After focus and dehydration, the trimerization is obtained glycerin;
( 2) Under a pressure of -0.09 MPaa, add 10 mol of tripolyglycerol and 0.1 mol of a compound mixed alkaline driver (a mix of NaOH and NaH2PO2 with a mass proportion of 1:1) into the response pot, mix equally, and heat to 60 ° C;-LRB- 3) Pour nitrogen into the action kettle, consist of 6 mol of recovered tristearate to the tripolyglycerol and material combined alkaline chauffeur blend symphonious (2 ), raise the temperature to 200 ° C and mix, and cool off after 6 hours of esterification response. Incredible to routine temperature to get solid tripolyglycerol monostearate.
Throughout the entire action procedure, nitrogen requires to be continuously replaced.
Advantages of this Technique:
1) This method resolves the problem of high production prices of conventional old treatments for many years. This method supplies the method for preparing Triglycerol Monostearate by reusing the byproducts ditriester and triglycerol created when the distilled monoglyceride supplier generates distilled monoglyceride., the price of the ditriester made use of is simply around 57% of that of stearic acid and about 85.7% of that of solidified oil. This prep job technique can effectively minimize the manufacturing expense of tripolyglycerol monostearate. Its procedure is fundamental and the issues are basic. Regulated, premium tripolyglycerol monostearate can be produced industrially in large quantities.
( 2) This approach prepares tripolyglycerol monostearate with an esterification response of tripolyglycerol and ditriester at warm, using alkali as an energizer. Compared to the regular process, it creates concerning 4% less wetness, therefore reducing manufacturing energy intake and pleasing the requirements of environment-friendly environmental management.
( 3) Throughout the response treatment of this method, nitrogen is utilized as the security gas and the decreasing rep NaH2PO2 or NaH2PO2 · water in the substance blended alkaline motorist, which can properly protect against the decay and darkening of saturated fatty acids at heats, and lessen the smell and smell of the product.
( 4) Triglycerol Monostearate and propylene glycol monostearate prepared by this strategy are worsened to get an emulsified structure of this method. This emulsified structure can be utilized in cakes to significantly increase the high quality of the cake, enhance the quantity of the cake, and make the cake much more The framework is fragile and soft.
