A new quantitative GLC method for analysis of lidamidine hydrochloride (I) was developed. The method was based on derivatization of I to 1 -(2,6-dimethylphenyl) -4-methylamino-dih ydro-1,3,5-triazin-2-one (11) using dimethylformamide dimethylacetal reagent. Compound
High water-absorbent polyacrylates could be prepared by concentrated aqueous solution polymerization within a short time period, heating the monomer mixture by water bath. The influences of initiator content, bath temperature, crosslinker content (Cc), and degree of neutralization on water absorbenc
