DMAC is mainly used for synthetic fibers（acrylonitrile）Solvent for polyurethane spinning and synthesis of polyamide resin, also used forC8 fraction is used as an extraction and distillation solvent for separating styrene, and is widely used in polymer films; Coatings and pharmaceuticals, etc. Currently, it is widely used for synthesis in pharmaceuticals and pesticidesantibioticsAnd pesticides and insecticides.2. Can be used as a catalyst for reactions; Electrolytic solvents; Paint removers and various crystalline solvent adductscomplex.3. Used as a solvent, paint remover, catalyst, and for organic synthesis.　1. Chemical properties andN. N-dimethylformamideVery similar, it is a representative amide solvent. When there is no acid or alkali present, it can be distilled at atmospheric pressure by heating to boiling without decomposition. The hydrolysis rate is very slow and containsWhen N, N-dimethylacetamide with 5% water is heated at 95 ℃ for 140 hours, only 0.02% undergoes hydrolysis. But in the presence of acid and alkali, the hydrolysis rate increases. When strong alkali is present, heating causes saponification.

Triple measurement and controlMSDR-MR90 typeDimethylacetamideDMAC online concentrationanalysisceremonyIt is an online concentration measuring instrument developed based on the principle of refraction. It has good stability, high accuracy, and wide measurement range for online concentration detection. Suitable for pipeline installation or installation on tank walls, as well as other installation methods, and can also customize systematic solutions according to customer needs. Adopting advanced optical device integrated design, the photoelectric signal is directly converted and processed, with high-precision automatic temperature compensation function, good seismic performance and high stability. Fully cast fiberglass shell and fully shielded steel plate inner wall design, online detection is not affected by impurities such as pressure, flow rate, color, turbidity, bubbles, solid particles, etc; The concentration detection value can be displayed on site, and the detection data can be obtained through4-20mA analog signal or RS485 communication signal is connected to PLC or DCS for automatic control and concentration adjustment, reducing the uncertainty caused by manual operation, eliminating concentration imbalance caused by human control, and achieving the effect of automatic and stable concentration control. Ensuring that the process concentration is strictly executed according to the process plan can significantly save human resources, improve product quality, enhance enterprise management level and production process control capability.

The concentration of a solution refers to a certain amount of solutionThe amount of solute contained in (or solvent), the traditional solution concentration analysis and measurement method is fully manual operation, which is easily affected by factors such as sampling environment, temperature changes, and manual operation, and cannot effectively guarantee the stable quality indicators of the product. Resulting in lagging production process control, low automation level, and inability to achieve real-time fully automatic monitoring and control of concentration.
