溴化钠 制备方法及用途
制备方法
-
尿素还原法将纯碱(碳酸钠)、尿素用热水溶解，并送入反应器中，缓慢加入溴素进行反应，生成溴化钠。然后再加入活性炭脱色，经过滤、蒸发结晶、离心分离、干燥，制得溴化钠成品。其反应方程式如下：中和法将约40％的氢溴酸加入反应器中，在搅拌下缓慢加入40％烧碱溶液进行中和，至Ph7.5～8时生成溴化钠，经离心分离、蒸发、结晶再离心分离，制得溴化钠成品。其反应方程式如下：3.碳酸钠、尿素用热水溶解，通入溴素，还原生成溴化钠，然后加入活性炭脱色、过滤、蒸发、结晶即得。4.将碳酸氢钠慢慢加到氢溴酸溶液中进行中和反应：加热赶出二氧化碳气体并浓缩溶液至结晶，然后冷却至室温，析出的结晶用少量水溶解，并滴加溴水至刚出现溴的颜色，加入硫化氢溶液进行脱色，加热蒸发浓缩结晶至干，高温析出无水溴化物。110℃下保温干燥后在保干器中冷却，即得无水溴化物。

Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Effects may be cumulative. May cause central nervous system effects such as psychosis, hallucinations, depression, visual changes and mental changes. Ingestion may cause skin eruptions and rash.
Inhalation:
May cause effects similar to those described for ingestion.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion. May cause incoordination and mental disturbances.
Section 4 - FIRST AID MEASURES
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid.
Notes to Physician:
Treatment includes hydration, mild diuresis, and possible hemodialysis. Consider the use of ammonium chloride in divided doses with a diuretic.
