Caldum hydroxide

The next stage is to predpitate the soluble dtric add as insoluble caldum dtrate using caldum hydroxide. 

A simplified scheme is shown in Figure 5.10. The fermentation mixture is filtered to remove mycelium and suspended solids. The solution is treated with hot carbon and then filtered. During the process addification is necessary to reverse the neutralisation by caldum hydroxide or ammonium hydroxide employed during fermentation.

Pentaersrthritol. To a mixture of 18.5 g. of caldum hydroxide and 75 g. of formaldehyde in 500 cc. of water is slowly added 22 g. of acetaldehyde. The temperature of the mixture is maintained at 15° during the addition of the acetaldehyde and then gradually raised to 45°. The calcium is precipitated with oxalic add, the calcium oxalate removed by filtration, and the filtrate evaporated to dryness under reduced pressure. The residue is taken up in 200 cc. of hot ethanol, and the resulting solution allowed to cool. The pentaerythritol which separates wei 50 g. (73.5% of the theoretical amoimt) and melts at 258°. Pure pentaerythritol melts at 260°. ...

Chlorohydrin Process, Ethylene oxide is produced from ethjiene chlorohydrin by dehydrochlorination using either sodium or caldum hydroxide (160). The by-products include calcium chloride, dichloroethane, bis(2-chloroeth5i) ether, and acetaldehyde. Although the chlorohydrin process appears simpler, its capital costs are higher, largely due to material of constmction considerations (197).

Chemicals can be added to soil to adjust its pH. Most often it is too add, so it is treated with quicklime (caldum oxide), slaked lime (caldum hydroxide), or chalk (caldum carbonate). These are all bases, and quite cheap. 

Caldum carbonate, caldum oxide, and caldum hydroxide are bases. They are also cheap. So farmers spread them in powder form on soil that is too addic. Calcium hydroxide is also added to liquid waste from factories, to neutralise any acids in it (page 123). 

During the sugar juice clarification (known as carbonation see Section 4.4.2.1.2) using caldum hydroxide, saccharose dissociates in an alkaline medium in several steps (at 25 °C pKj = 12.60 pK2 = 13.52 pXj = 13.72 = 13.77). The most reactive atoms...
