Research and Manufacture of Red Fuming Nitric Acid/ UDMH Gel Bipropellant 国外水下液体化学推进剂的研究现状红烟硝酸/偏二甲肼凝胶双组元推进剂研制
Its main synthesis method is nitration of guaiacol by fuming nitric acid and glacial acetic acid as nitration agent. 它的合成目前主要采用愈创木酚硝化法,以发烟硝酸和冰醋酸混酸做硝化剂。
A yellow fuming corrosive mixture of nitric and hydrochloric acid that dissolves metals ( including gold). 一种黄色、气味浓烈、腐蚀性的氮和盐酸的混合物,能溶解金属(包括金)。
Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents. 能安全使用于除熔化碱金属、氟溶液、发烟酸及其它强氧化性介质以外的一切化工泵,也适合于水、蒸汽、植物油、溶剂等介质。
Methods: Isoquinoline as material was oxidized with fuming nitric acid instead of the reported concentrated nitric acid to synthesize target compound. 方法:以发烟硝酸代替文献报道的浓硝酸作氧化剂,异喹啉为原料,氧化合成目标产物。
Development of protective gloves for red fuming nitric acid 红烟硝酸防护手套的研制
Study on improving the determination method of nitrogen tetroxide in red fuming nitric acid 红烟硝酸中四氧化二氮含量测定方法改进研究
Welding procedure of fuming nitric acid absorber made of c_4 steel C4钢制发烟硝酸吸收塔焊接工艺
Under no adding oxidant and no using fuming nitric acid, nitric acid can be intercalated into graphite fiber by anodic oxidation method, thus the electrie resistivity of the graphite fiber will be decreased. 用阳极氧化法可以在不添加氧化剂和不使用发烟硝酸的情况下,将NO3~-插入石墨纤维中,降低石墨纤维的电阻率。
The effect of Oleum concentration, Molar ratio of fuming nitric acid with DAP, nitrification temperature and extraction methods to the reaction were been studied. 对发烟硫酸浓度、发烟硝酸和DAP摩尔比、硝化温度、萃取方式等多个方面对反应的影响进行了研究。
