Properties and stability

Storage method

Refrigeration should be stored in a cool, dry place. Store in an airtight container. Low temperature preservation

Synthesis method

1. Acryloyl chloride and isopropylamine are used as raw materials and reacted under the conditions of ethyl acetate. C₃H₇NH₂+CH₂CHCOCl——CH₂＝ CHCONHCH(CH₃)₂+HCl uses ethyl acetate or benzene as the medium, and isopropylamine (IPA) and acryloyl chloride (ACC) as raw materials. Obtain CH₂=CHCONHCH(CH₃)₂ crude product, and then recrystallize it through n-hexane to obtain high-purity CH₂ sub>=CHCONHCH(CH₃)₂. The yield is approximately 88%. 2. Acrylonitrile and isopropyl alcohol are used as raw materials and react under concentrated sulfuric acid conditions. CH₂=CHCN+(CH₃)₂CHOHCH₂—–CHCONHCH(CH₃)

Mix 0.15 mol acrylonitrile, 0.15 mol isopropanol, 3×10^-4mol parahydroxyanisole and pour into a 250mL four-necked flask , pour 0.45 mol of concentrated sulfuric acid into the funnel and drip it from one side port. A thermometer and a condenser tube are installed at the other two side ports. A stirrer is installed in the middle bottle mouth, and the stirring speed is controlled at 100r/min. Adjust the dripping speed of concentrated sulfuric acid in the funnel so that the control temperature in the reaction bottle is between 55 and 65°C. The dripping time is about 60 minutes. After continuing the reaction for 30 minutes, the color of the reaction solution will be light yellow.

The reaction solution is neutralized with ammonia water to pH=1~2. After neutralization, the reaction solution is divided into three layers. The water layer and the oil layer are put into two beakers respectively. The water layer is fully frozen to make NIPAM single. The solid crystallizes and floats on the water layer, and the ammonium sulfate crystals precipitate at the bottom of the beaker; the oil layer is fully frozen to make it agglomerate. Then, the oil layer agglomerates and the water layer NIPAM crystals are filtered under reduced pressure and placed in a vacuum oven to dry at room temperature. Then use benzene-n-hexane mixed solvent to recrystallize at least 3 times to obtain white crystalline NIPAM with a yield of 54.2%.

Purpose

N-Isopropylacrylamide is an acrylamide derivative monomer. Due to the hydrophilic amide group and hydrophobic isopropyl group in the molecule, the homopolymer has a low critical solution temperature and other good properties. Characteristics, mainly used to manufacture polymer gels with temperature-sensitive properties, such as: drug controlled release materials, enzyme solid materials, dehydrating agents, concentrates, etc. It can also be used to make modified latex, special coatings, adhesives, etc.

Storage method

Plastic bag coated with woven bag or kraft paper bag. Store in a cool and dry place.

Synthesis method

1. Glucose is one of the most abundant compounds in nature and is a product of photosynthesis. It exists in free form in plant juices, especially in fruits, honey, plasma, and lymph. The glucose content in normal human blood is 0.08%-0.1%, and a larger amount of it exists in the form of combined sucrose, starch, glycogen, cellulose and glycosides. Initially glucose was separated and crystallized from grape juice, hence its name. Industrially produced glucose is produced by hydrolysis of starch. In the past, dilute hydrochloric acid was used to hydrolyze starch. Now, dilute hydrochloric acid is almost completely replaced by enzymatic hydrolysis.

2.Starch can be hydrolyzed to obtain glucose.

Purpose

1. Can be used as nutritional sweeteners, water retaining agents, texture improvers, molding and processing aids.

2. Can be used as reducing agent, biological culture medium and biochemical reagents.

Properties and stability

Rapid intravenous injection can quickly degrade into 5-fluorouracil, with the same effects and side effects as 5-fluorouracil. Continuous arterial infusion can be directly converted into 5-fluorodeoxyurea, thereby inhibiting DNA synthesis. Effective results can be obtained with a smaller dose, which is three times higher than rapid intravenous infusion.

Storage method

This product should be sealed with argon gas and stored at 0~4℃.

Synthesis method

Methyl-2-deoxy-D-ribofuranoside is p-toluoylated and hydrolyzed with acetic acid-hydrochloric acid to replace the methoxy group at position 1 with chlorine, and then combined with 1 – The condensation of mercury acetoxy-5-fluorouracil is obtained by hydrolyzing the product to remove the p-toluyl group.

Purpose
