Preserving Waterlogged Archaeological Pine Wood

Check if the same lab product or an alternative is used in the 5 most similar protocols
Waterlogged archaeological pine wood (Pinus massoniana) were cut into blocks of 10 mm (longitudinal), ×5 mm (tangential) and ×5 mm (radial) approximately in size. The archaeological wood used was obtained from the Nanhai One shipwreck lying on the bottom of South China Sea for around 800 years with a maximum moisture content of around 529%. These sample were desalinated before the treatment. However, the indissoluble salts including calcium sulfate and ferrous sulfide can be hardly removed from the samples. Anisole(99%), copper(II) bromide(Cu(II)Br2, 99%) from Macklin Biochemical, 2-bromoisobutyryl bromide (BIBB, 98%) from Bide Pharmatech, N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA, 98%), 2-Bromo-2-methylpropanoic acid (97%) from D&B Biotech, pyridine (99%), Ascorbic acid (Vc, 99%) from Xilong Scientific, ethanol (AR) and dichloromethane (CH2Cl2) from Tongguang Fine Chemicals were used directly without purification. Butyl methacrylate (97% with 10 ppm MEHQ) and styrene (99.5%) were purchased from Aladdin and purified through an alkaline aluminum oxide column to eliminate inhibitors before use.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
