Dmp Phthalate Uses
Dmp Phthalate is a plasticizer with strong solubility for various resins, as well as is compatible with various cellulose materials, resins, along with plastic materials. It has great film-forming, sticky as well as water resistant household or business buildings. It is normally utilized in combine with Dmp Phthalate in the production of cellulose acetate movie, varnish, clear paper and also molding powder. A percentage is used in the production of nitrocellulose. The item can likewise be used as a plasticizer for dingteng periodontal tissue, and also the product has wonderful cool resistance. Mixed with various other plasticizers. It can remove the drawbacks of high volatility and decreased temperature condensation. The item can similarly be made use of as a solvent for making jiao oil (petroleum) and also DDT. The item is likewise made use of as gas phase Chromatographic fixative.
This item is a plasticizer with strong dissolving power for various materials, ideal with many cellulose resins, rubber in addition to plastic resins, in addition to has excellent film-forming, glue along with water-proof houses.It is commonly utilized in combination with Dmp Phthalate in the manufacturing of cellulose acetate movie, varnish, transparent paper as well as similarly molding powder. A percent is made use of in the production of nitrocellulose.
Dmp Phthalate Production Method
Atmospheric pressure esterification is carried out by phthalic anhydride and excess (4 times) methanol, and excess methanol is refluxed with water to react to obtain DMP. Put 600kg of phthalic anhydride, 450kg of methanol at 90-95°C, and 1050ml of concentrated sulfuric acid into the reaction pot in sequence, and heat to reflux for 24 hours. After the reaction, methanol is recovered, then neutralized with sodium carbonate, washed with water, and then distilled to obtain the finished product. The purity of Dmp Phthalate, the first-class industrial product, is ≥99%. Raw material consumption quota: phthalic anhydride 750kg/t, methanol 445kg/t.
Preparation Method of Mosquito Repellent

Prep Work
The synthesis of mosquito repellent is primarily separated right into 2 actions. First, butylamine and also ethyl acrylate are contributed to synthesize ethyl 3-n-butylaminopropionate; then, ethyl 3-n-butylaminopropionate is reacted with acetic anhydride to create mosquito repellent. The reaction equation is as adheres to:
1) Synthesis of ethyl 3-n-butylaminopropionate: Include 438 (6.0 mol) grams of n-butylamine right into a 1000 mL three-necked flask, warmth to reflux, and add 100 g (1.0 mol) of ethyl acrylate dropwise under mixing problems. After the dropwise addition, remain to mix and also keep warm for 3 to 4 hours, and track the response with gas chromatography. After the reaction, make use of a rotating evaporator to remove excess n-butylamine, and afterwards fractionate under decreased stress with an oil pump to acquire 158 grams of ethyl 3-n-butylaminopropionate, with a yield of 91.3% as well as a content of more than 99.5%.
2) Synthesis of mosquito repellent: Include 173 g (1.0 mol) of the intermediate 3-n-butylaminopropionate into a 500 mL three-neck bottle, control the internal temperature level between 80 as well as 90 ° C, as well as add acetic anhydride dropwise under mixing 132 grams (1.2 mol), after the dropwise enhancement was completed, the response was continued for 1 hour. After the reaction is over, the water pump decompresses and also recoups acetic acid as well as unreacted acetic anhydride till the internal temperature level gets to 100-105 levels, and then fractionates and also decompresses with an oil pump to get 201 grams of completed product with a return of 93.7% as well as a purity of 99.8%. It is clear in shade as well as essentially odorless. The product was identified as insect repellent by HNMR, CNMR as well as GCMS.
Check
An approach for detecting and also evaluating insect repellent web content, making up the following actions:
( 1) prepare the typical sample service of mosquito repellent ester, ( 2) prepare the interior typical solution of dimethyl phthalate, ( 3) The common sample service is mixed with the inner typical service symmetrical to prepare a combined typical remedy, ( 4) the blended typical solution prepared by action (3) is put in the gas chromatograph for example shot, the weight focus ratio of mosquito repellent and dimethyl phthalate is the abscissa, and the weight focus ratio of insect repellent and also phthalate The dimethyl formate optimal location proportion is the ordinate, as well as the internal basic contour is drawn;
( 5) prepare a sample remedy comprising insect repellent, ( 6) adding an inner typical solution to the sample option prepared in step (5) to obtain a mixed example remedy, ( 7) The mixed example service prepared by action (6) is placed in a gas chromatograph for sample injection, and also the sample reads on the inner conventional common curve with the insect repellent and dimethyl phthalate top location proportion in the mixed sample remedy The weight focus ratio of the insect repellent ester and dimethyl phthalate of the option is used to calculate the insect repellent ester material in the mixed example remedy.
