硫化钠 制备方法及用途

制备方法

用于制造硫化染料或染料中间体,还原剂,媒染剂。冶金工业中用作矿石的浮选剂,皮革工业中的脱毛剂,造纸工业中的蒸煮剂。也广泛用于颜料、橡胶等工业中。

合成制备方法

1.煤粉还原法

用途简介

用途

1.染料工业中用于生产硫化染料,是硫化青和硫化蓝的原料。印染工业用作溶解硫化染料的助染剂。制革工业中用于水解使生皮脱毛,还用以配制多硫化钠以加速干皮浸水助软。造纸工业用作纸张的蒸煮剂。纺织工业用于人造纤维脱硝和硝化物的还原,以及棉织物染色的媒染剂。制药工业用于生产非那西丁等解热药。此外还用于制硫代硫酸钠、硫氢化钠、多硫化钠等。

2.在铝及合金碱性蚀刻溶液中添加适量的硫化钠可明显改善蚀刻表面质量,同时也可用于碱性蚀刻液中锌等碱溶性重金属杂质的去除。

3.硫化钠还可用于直接电镀中导电层的处理,通过硫化钠与钯反应生成胶体硫化钯来达到在非金属表面形成良好导电层的目的。

4.用作缓蚀剂。也是硫代硫酸钠、多硫化钠、硫化染料等的原料。

5.用于制造硫化染料,皮革脱毛剂,金属冶炼,照相,人造丝脱硝等。[15]

Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Contact with acids liberates toxic gas. Causes burns. Very toxic to aquatic organisms.Corrosive.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Causes eye burns. May cause irreversible eye injury. May cause blindness. May cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. May be absorbed through the skin in harmful amounts. Prolonged and/or repeated contact may cause irritation and/or dermatitis. Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. May cause perforation of the digestive tract. May cause cardiac disturbances.
May cause systemic effects.
Inhalation:
May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract. May cause effects similar to those described for ingestion. Aspiration may lead to pulmonary edema. May cause systemic effects.
Chronic:
Effects may be delayed.

Section 4 - FIRST AID MEASURES
  Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. 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:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Wash hands before eating. Use only in a well-ventilated area. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Keep away from heat, sparks and flame. Do not ingest or inhale. Discard contaminated shoes.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
Store in a tightly closed container. Keep from contact with oxidizing materials. Keep away from strong acids. Store protected from moisture.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 1313-82-2: Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use. Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
