A preparing method of a hydroxymethyl impurity of adefovir dipivoxil is provided. The method includes S1) a step of preparing crude hydroxymethyl impurity of the adefovir dipivoxil, with the crude hydroxymethyl impurity being prepared from 2.5-4.0 parts by weight of N-methyl-2-pyrrolidone, 1.0 part by weight of adefovir A-4, 1.0-1.5 parts by weight of triethylamine and 2.0-3.6 parts by weight of chloromethyl pivalate, S2) a step of filtering a crude adefovir dipivoxil compound solution for purification, and S3) a step of subjecting the crude adefovir dipivoxil compound dry product prepared in the step S2) to secondary crystallization for purification.

The invention relates to a method for knitting a 2*2 rib stitch textile through a two-needle bar flat knitting machine and belongs to the technical field of a knitting method in a flat knitting machine. According to the method, cylindrical knitting in an alternate needle mode is performed on front and rear needle bars of the two-needle bar knitting machine; when a front piece is knitted, odd needles or even needles of the front needle bar are adopted; when a rear piece is knitted, the odd or even needles of the rear needle bar are adopted; during a knitting process, the knitting in the alternating mode that one line is woven at the front and one line is woven at the back is adopted; the method is characterized in that at least two yarn nozzles are used; the two yarn nozzles are respectively represented by Y1 and Y2; Y1 is used for representing waste yarns or drawn yarns; Y2 is used for representing main yarns; eight needles are taken as one circle of rib stitch; the needles on the front needle bar are successively named as a, b, c, d, e, f, g, h and so on from left to right; the needles on the rear needle bar are successively named as a', b', c' d', e', f', g' h' and so on from left to right. The front and rear cut pieces are kept separated; the rib stitch starting opening is compact and attractive; the quality of the rib stitch textile is increased.
