制备氯化氫甲醇溶液的方法

返回打印发布时间：2015/11/18 点击：13344

    無水氯化氫气体的甲醇溶液工業級和試劑都有得賣的，一般爲其飽和溶液。制備的話對于一般的實驗室來說還是很容易方便的。
    将氯化钠置于三口瓶中，三口瓶再连接一个导气管到一个装有甲醇的试剂瓶中，中间最好加一个干燥装置，接收氯化氫的装置需要冷却。再缓慢的将浓硫酸滴加进来，产生的氯化氫溶解于甲醇溶液中。滴加前将甲醇称好重，根据滴加前后的重量可以得出多少ml的甲醇吸收了多少氯化氫。实际上甲醇还是有挥发的，最好是氯化氫過量，通至其飽和。然後根據需要再用甲醇稀釋。
    下面是氯化氫在甲醇中的饱和溶解度数据。
    Soly in methanol(g/100 g soln):54.6(-10度);51.3(0度);47.0(20度);43.0(30度)
    我制備的方法是將鹽酸置于裝有機械攪拌和滴液漏鬥(濃硫酸)的燒瓶中,燒瓶上的出氣口可用溫度計套管,中間裝有幹燥裝置(濃硫酸,氯化鈣的幹燥塔),接收裝置(一般我用燒瓶,密閉性好,都是標准口,一頭裝個導氣管通入甲醇中,另一頭可視通氣速度大小裝個幹燥器),用橡皮管連接發生裝置,幹燥裝置和接受裝置!
    淄博万达利特种气体公司生产的氯化氫是在淄博齐鲁石化工业园区注册的高新科技企业，淄博万达利直属于北京华宇同方，主要从事新材料技术和化工新技术的研发，以及高新技术产品的生产和销售。研发的沸石催化剂及其应用技术处于世界先进水平。生产的“华宇同方”牌高纯氯化氫産品與國際知名品牌的性能相當，爲半導體器件制造業、光伏産業和醫藥工業提供了充足的優質原材料。

Then suddenly all surmise and speculation was expunged from his mind, for no longer the clack of the typewriting machine came from next door. He heard the stir of a chair pushed back, and the rattle of a door handle. Norah was coming; who was of greater concern than all his thoughts about her.... And he was going to give her no quarter: she would have to introduce the subject of her feelings with regard to his niggardly hospital-subscription herself. He knew something of her pride from the affair of the book-plate, and he longed to see her take that armour off. "Found anything out, mate?" another officer asked. It is not intended to recommend writing down rules or tables relating to shop manipulation so much as facts which require remark or comment to impress them on the memory; writing notes not only assists in committing the subjects to memory, but cultivates a power of composing technical descriptions, a very necessary part of an engineering education. Specifications for engineering work are a most difficult kind of composition and may be made long, tedious, and irrelevant, or concise and lucid. From a quite small garden close to the palace a bronze gate with three medallions of lilies in high relief, of marvellous workmanship, opens on the Pearl Mosque, exquisitely white, at the end of its forecourt of immaculate pavement enclosed by a marble balustrade. Three polished and shining domes are supported by columns of snow made of a hard white marble, scarcely broken by [Pg 218]ornament, and carrying a roof hollowed into three vaults. The rings are still to be seen on the marble walls outside, to which, when the great Mogul came to prayer, curtains were attached made of gold net and spangled with diamonds and pearls. Sandy’s birthday dawned hot, but clear, with a good, steady south wind blowing. “Jeff calls it a ‘jinx’—a ‘hoodoo’,” responded Dick. “But the chef would discover it—they couldn’t be left there!” She was sitting in her room, sewing. Of late she had become domesticated, and she was fading under it. He had seen it already, and he saw it more plainly than ever just now. She looked up and smiled. Her smile had always been one of her greatest charms, because it was rare and very sweet. "Jack," she greeted him, "what have you done with the bread knife you took with you, dear? I have been lost without it." "Neither," drawled Cairness. "But Mrs. Lawton, here, has been good enough to tell me that you have known the exact truth about the Kirby massacre ever since a week after its occurrence, and yet you have shielded the criminals and lied in the papers. Then, too," he went on, "though there is no real proof against you, and you undoubtedly did handle it very well, I know that it was you that set Lawton on to try and bribe for the beef contract. You see your friends are unsafe, Mr. Stone, and I have been around yours and Lawton's ranches enough to have picked up a few damaging facts." The prince found in the Opposition in England the most unfortunate fosterers of his unfilial temper. Pulteney, Wyndham, Chesterfield, Carteret, Cobham, and, worst of all, Bolingbroke, became his associates, and the frequenters of his house. Fast ripening into a pattern of unfilial popularity under such influences, possessing some accomplishments, and a desire to stand well with the people, he married in April, 1736, Augusta of Saxe-Gotha, a princess of so much beauty and good sense, as might have reclaimed many a nature; who seems to have at least won the heart of her husband from his former romantic passion. It was an ominous circumstance, however, that the address of congratulation on this occasion was moved, not by the king's own Ministers, but by the king's own Opposition. Pulteney was the mover, and it was supported by two young men who that evening made their first speeches, and in them burst suddenly forth with that splendour which was destined to grow transcendent through many years. They were Pitt, afterwards Lord Chatham, and Lord Lyttelton. The Deacon had just remembered that he had not seen that individual for some little time, and looked around for him with some concern. It was well that he did. Shorty had come across the haversack that the Deacon had brought, and it awakened all his old predatory instincts, sharpened, if anything, by his feebleness. Without saying a word to any body, he had employed the time while the Surgeon and Deacon were in conversation in preparing one of his customary gorges after a long, hard march. He nearly succeeded. There was silence, in which a coal fell. She still stood with her arms outstretched; he knew that she was calling him—as no woman had ever called him—with all that of herself which was in his heart, part of his own being. "Why, my lord," said Luke, in reply to De Boteler's interrogatory, "there is hardly a free maiden in the parish that would not have been glad of Stephen; but, though I have never seen her, I am told this wife of his is the comeliest damsel between this and Winchcombe: and, besides, she is not like a common nief—and then, my lord, she is the sister of the good monk John."
