代谢
金属磷化物被水解成磷化氢和相应的金属阳离子...在大鼠体内,未通过呼出气体排出的磷化氢被氧化,并出现在尿液中,主要是作为次磷酸盐和磷酸盐...还报道了一种通过纸色谱法检测到且与焦磷酸和偏磷酸不同的未识别代谢物。事实表明:(a) 磷化氢并未完全氧化;(b) 随着剂量的增加,通过呼出气体排出的磷化氢占给药剂量的比例增加,这表明氧化途径是缓慢的。
Metal phosphides are hydrolyzed to phosphine and the corresponding metal cation ... In rats, phosphine that is not excreted in the expired air is oxidized and appears in the urine, chiefly as hypophosphite and phosphite ... An unidentified metabolite, detectable by paper chromatography and distinct from pyrophosphate and metaphosphate /was also reported/. The fact that (a) phosphine is incompletely oxidized; and (b) the proportion of an administered dose that is eliminated as expired phosphine increases with the dose suggests that the oxidative pathway is slow.

毒理性
  • 解毒与急救
立即急救:确保已经进行了充分去污。如果患者停止呼吸,开始人工呼吸,最好使用需求阀复苏器、气囊面罩装置或口袋面罩,按训练进行操作。根据需要执行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果发生呕吐,让患者前倾或置于左侧(如果可能的话,头部向下)以保持呼吸道畅通,防止吸入。保持患者安静,维持正常体温。寻求医疗帮助。/镁及相关化合物/
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Magnesium and Related Compounds/

制备方法与用途

合成制备方法

3Mg + 2P → Mg₃P₂

使用氢气流携带磷蒸气通过热镁粉制得Mg₃P₂。进行反应的仪器装置如图Ⅱ-5所示:1和2为硬质玻璃制成的反应舟,其中1装有5克红磷,2装有4克不含氧化镁的纯镁粉。通过活塞3抽真空并通入H₂,出口4为氢气出口,分别用电炉5和6加热舟1和舟2。初始温度设定为600℃,反应结束时将温度提升至700℃以驱除过量的磷。

在舟2中生成了Mg₃P₂结晶,在继续通入H₂的情况下打开管口4,用玻璃棒将舟1和舟2推至管端8处,再将舟2拉回十字口9处,翻转舟2使磷化镁落入竖管下端10。封闭管口4后,打开竖管端口11,伸入玻璃棒捣碎10处的Mg₃P₂。在持续通氢气的情况下,将磨口12以下部分取下,并立即用磨口帽封闭磨口12。通过活塞3连接黄铜皱纹管与真空泵和H₂发生器(不可使用橡皮管,因为可能会释放湿气)。倾斜装置使Mg₃P₂粉末倒入球形小瓶13和毛细管试样管14中,并将其熔封保存。

    Quinazoline derivatives, substituted in the 2-position by the residue of a cyclic (especially heterocyclic) amino compound of aromatic character (particularly an aminothiazole compound) and in the 4-position by the residue of an amino compound of aliphatic character (the aliphatic chain of which may be interrupted by a hetero atom such as oxygen or sulphur) containing a further strongly basic group (e.g. a dialkylamino, piperidino or morpholino group), are manufactured by heating a 2 : 4-dihalogenquinazoline (which may contain further substituents) with the two amines simultaneously, advantageously in the presence of a diluent (e.g. water, alcohol, dioxane or nitrobenzene), if desired under pressure. Examples describe the reaction of 2 : 4-dichloroquinazoline with b -diethylaminoethylamine and simultaneously with: (1) 2-amino-4-phenylthiazole; (2) and (3) p-chloraniline. Lists are given of further products, involving the following additional reactants: 2 : 4 : 6-trichloroquinazoline; 2-aminobenzthiazole and its 6-methyl, chloro, methoxy, nitro, cyano, n-butoxy, acetylamino, methylsulphonyl, benzyl, sulphonamido and phenoxy derivatives, 2-amino-4-methyl- and -4 : 7- and -4 : 6-dimethyl-benzthiazole, 2-aminothiazole, 2-aminobenzimidazole and its 6-methyl derivative, 2 - amino - 6 : 7 - benzobenzthiazole, 2 - amino - 4 - (p - tolyl) - and - 4 - (p - bromophenyl) - thiazole, 2 - amino - 4 : 5 - diphenylthiazole, p - toluidine, p - anisidine, and b - naphthylamine; g -diethylaminopropylamine, b -piperidinoethylamine, 1 - diethylamino - 3 - butylamine, and b - (b 1 - diethylaminoethylthio)-ethylamine.
