    摘要: An igniter shield for use in combination with an igniter includes a substantially cylindrical-shaped body that includes a proximal portion, a distal portion, a first longitudinally oriented support and a second longitudinally oriented support, wherein the first and second longitudinally oriented supports extend between and are connected to the proximal portion and the distal portion, the substantially cylindrical-shaped body further including a longitudinally oriented baffle circumferentially spaced apart from the first and second longitudinally oriented supports, wherein the baffle extends between and is connected to the proximal portion and the distal portion, and wherein the baffle includes a radially outward facing convex surface and a radially inward facing concave surface, the radially inward facing concave surface having a radius of curvature smaller than a radius of curvature of at least one of the proximal or distal portions.

    摘要: Disclosed is a method for preparing benidipine hydrochloride, which comprising: 1) during the pre-treatment stage including acylchloridizing the main ring of dihydropyridine and then linking the side chain to synthesize directly benidipine hydrochloride, ultrasound technology is introduced, and the reactant material is dispersed and dissolved by untrasound to increase reaction rate; and/or 2) during the post-treatment stage, ultrasound technology is introduced and crude crystals or product obtained by heating to dryness of benidipine hydrochloride obtained via the method described above or any other synthetic routes is dissolved once more and then highly purified benidipine hydrochloride is obtained by untrasound.
