D-泛酸钙 制备方法及用途

制备方法

1、由异丁醛经甲醛羟甲基化、加成、水解、酸化、内酯化、酰化、加成而得。 2、由丙烯腈、氨、氢氧化钠、氧化钙反应生成的β-氨基丙酸钙与由异丁醛、甲醛、氰化钠反应生成的α-羟基-β,β-二甲基-γ-丁内酯制得DL-泛酸钙,再经拆分制得。

合成制备方法

1、由异丁醛经甲醛羟甲基化、加成、水解、酸化、内酯化、酰化、加成而得。

2、由丙烯腈、氨、氢氧化钠、氧化钙反应生成的β-氨基丙酸钙与由异丁醛、甲醛、氰化钠反应生成的α-羟基-β,β-二甲基-γ-丁内酯制得DL-泛酸钙,再经拆分制得。

用途简介

泛酸在体内参与基本代谢功能,参与脂肪酸的合成,降解并释放出大量能量,促进那些对病原体有抵抗力的抗体的合成,促进人体对各种营养物质的吸收和利用。泛酸的不足,可使许多器官和组织受损,表现出皮肤和粘膜发生病变、发炎;肠道和呼吸道易患疾病,生殖机能紊乱,生长缓慢,体重减轻,神经系统紊乱,抗体形成受到抑制。

用途

1、本品为维生素类药物,是辅酶A的组成部分。在混旋泛酸钙中,只有右旋体具有维生素活性,参与蛋白质、脂肪、糖在体内的新陈代谢。用于维生素B缺乏症及周围神经炎,以及手术后的肠绞痛。与维生素C合用可治疗播散性红斑狼疮。人体缺乏泛酸钙具有如下症状:(1)生长停止,体重减少,突然死亡。(2)皮肤、毛发障碍。(3)神经系统障碍。(4)消化器官失常,肝功能障碍。(5)影响抗体形成。(6)副肾障碍。每天人体需要泛酸钙(以泛酸计)约5mg。

2、营养补充剂。主要用于医药、食品添加剂及饲料添加剂,是人体和动物维持正常生理不可缺少的微量物质。除特殊营养食品外,使用量须在1%(以钙计)以下。奶粉强化时为10mg/100g;烧酒、威士忌酒中添加0.02%可增强风味;蜂蜜中添加0.02%可防止冬季结晶;可缓冲咖啡因及糖精等的苦味。

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. Dusts at sufficient concentrations can form explosive mixtures with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Do NOT get water inside containers. Use water spray, dry chemical, carbon dioxide, or appropriate foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation. Do not get water inside containers.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Avoid contact with air and sunlight. Keep from contact with moist air and steam.
Storage:
Do not store in direct sunlight. Keep refrigerated. (Store below 4C/39F.) Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from moisture. Store protected from light and air.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits CAS# 137-08-6: 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 prevent skin exposure.
Respirators:
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.
