一般說明
锂是一种低密度碱金属，广泛用作可充电和不可充电电池的负极材料。此外，它还可用于与铝和镁铸成合金，使其结构更坚固、更轻质。
颗粒锂是一种磨成小颗粒的锂金属。锂是一种质地柔软的银白色金属，具有高反应活性和易燃性。锂的密度很低，为0.534 g/cm3，是最轻的金属之一。和其他碱金属一样，锂的熔点很低（180°C），是电和热的良导体。 颗粒锂具有高反应活性，是一种强还原剂。它可能发生点燃或爆炸，因此必须谨慎处理。锂容易与水和氧气分别反应生成氢氧化锂和氧化锂，甚至在室温下可与氮气反应生成氮化锂。通常，锂储存于氩手套箱和密封容器中，以防止其暴露于湿气、空气和氮气中。 要制成颗粒锂，首先采用碳酸锂转换工艺从锂辉石或锂云母等矿石中提取金属。将锂纯化至高纯度后，通过旋转叶片将其磨成颗粒。

An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration-oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.

Are there trace amounts of mineral oil on this lithium? How is it handelled prior to being bottled under argon? After production, is argon the only inert atmosphere used?

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Greeting! Where could i found expiration date?
1 answer-
This product is not assigned an expiration date or recommended retest date. Products with no expiration date or recommended retest date should be routinely inspected by customers to ensure they perform as expected. These products are also subject to a one-year warranty from the date of shipment.
