存储与注意事项

1. 在您收到产品后请检查产品。如无问题，请将产品存入冰霜并且样品瓶保持密封，产品可以存放长达24个月（2-8摄氏度）。

2. 只要有可能，产品溶解后，您应该在同一天应用于您的实验。但是，如果您需要提前做预实验，或者需要全部溶解，我们建议您将溶液以等分试样的形式存放在-20℃的密封小瓶中。通常，这些可用于长达两周。使用前，打开样品瓶前，我们建议您将产品平衡至室温至少1小时。

3. 需要更多关于溶解度，使用和处理的建议？请发送电子邮件至：service@chemfaces.com

In Situ Catalytic Hydrogenation of Biomass-Derived Methyl Levulinate to γ-Valerolactone in Methanol.[Pubmed: 25873556]

METHODS AND RESULTS:
In this work, the hydrocyclization of methyl levulinate (ML) to γ-valerolactone (GVL) was performed in MeOH over an in situ prepared nanocopper catalyst without external H2 . This nanocopper catalyst served as a dual-functional catalyst for both hydrogen production by MeOH reforming and hydrogenation of ML. Nearly quantitative ML conversion with a GVL selectivity of 87.6 % was achieved at 240 °C in 1 h in MeOH under a nitrogen atmosphere. ML in the methanolysis products of cellulose also could be hydrogenated effectively to GVL over this nanocopper catalyst even in the presence of humins to give an ML conversion of 94.1 % and a GVL selectivity of 73.2 % at 240 °C in 4 h.
CONCLUSIONS:
The absorption behavior of humins on the surface of the nanocopper catalyst was observed, which resulted in a pronounced increase in the acidic sites of the nanocopper catalyst that facilitate ring-opening and the hydrocarboxylation/alkoxycarbonylation of GVL to byproducts.

One-pot preparation of methyl levulinate from catalytic alcoholysis of cellulose in near-critical methanol.[Pubmed: 22841826]

One-pot preparation of methyl levulinate (MLA) from cellulose in near-critical methanol was studied.
METHODS AND RESULTS:
Acids containing SO(3)H group were proven to be effective catalysts for the production of MLA from cellulose's catalytic alcoholysis. The effects of different reaction conditions, such as an initial cellulose concentration of 10-30 g/L, a temperature range from 170 to 190°C, and a sulfuric acid concentration of 0.01-0.03 mol/L, on the production of MLA were investigated.
CONCLUSIONS:
The results showed the reaction temperature and acid concentration significantly affected the process of cellulose alcoholysis and the yield of MLA. A high yield of up to 55% MLA was achieved at 190°C for 5h, using 0.02 mol/L H(2)SO(4) as a catalyst.
