Application of 73334-07-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 73334-07-3, name is N1,N3-Bis(2,3-dihydroxypropyl)-2,4,6-triiodo-5-(2-methoxyacetamido)-N1-methylisophthalamide belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

280 g of iopromide-K2 from Example 1 is dissolved in 520 g of water. The solution is then pumped at a volumetric flow rate of 3 ml/minute through a flow pipe that is provided with a pressurization valve of 20 bar at 208-209 C. The flow pipe that is used has an inside diameter of 1.7526 mm and a heated length of 5.5 m (see FIG. 1). A solution of the isomerized iopromide secondary crystallizate is then purified via ion-exchange columns and crystallized from ethanol. The yield of the iopromide that is crystallized from ethanol is approximately 80% of the experiment relative to the secondary crystallizate that is used in the isomerization.

The synthetic route of N1,N3-Bis(2,3-dihydroxypropyl)-2,4,6-triiodo-5-(2-methoxyacetamido)-N1-methylisophthalamide has been constantly updated, and we look forward to future research findings.

Adding some certain compound to certain chemical reactions, such as: 73334-07-3, name is N1,N3-Bis(2,3-dihydroxypropyl)-2,4,6-triiodo-5-(2-methoxyacetamido)-N1-methylisophthalamide, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 73334-07-3. 73334-07-3

12,000 g of iopromide, pure mother liquor (solid content about 6.2%), is concentrated by evaporation in a vacuum to form viscous oil of 892 g. 877 g of this residue is mixed in a suitable reaction vessel at a bath temperature of 65 C. with 439 ml of 1-propanol while being stirred. After inoculation with 0.73 g of iopromide, it is fully stirred for another 48 hours at a bath temperature of 65 C. The crystal suspension is then cooled to 20 C., stirred for I hour at this temperature and suctioned off via a suction filter. After washing with 4 portions of 110 ml of ethanol, the secondary crystallizate is dried at 40 C. in a vacuum-drying oven. Yield: 363.8 g (about 52% of the experiment)

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of N1,N3-Bis(2,3-dihydroxypropyl)-2,4,6-triiodo-5-(2-methoxyacetamido)-N1-methylisophthalamide.
