  15. Hunter Process (1/3)
  16.  
  17. A production level all about extracting titanium out of titanium dioxide, using the Hunter process:
  18.  
  19. <http://en.wikipedia.org/wiki/Hunter_process>
  20.  
  21. Solving this level is straightforward, since the reactor quota is generous and there's a recycler. Optimizing it may be a little more interesting.

  33. (NEW!) Not Road Salt (1/3)
  34.  
  35. I'm sure all of you are by now familiar with sodium chloride, NaCl, which is widely used as road salt due to its colligative properties when dissolved in water (from melted snow). Potassium chloride, KCl, is also used for this job.
  36.  
  37. Cesium iodide, CsI, is another salt made from a (heavy) group I element and a (heavy) halogen. At this time, SpaceChem has no plans to deploy CsI as road salt.
  38.  
  39. Phosphoric acid isn't road salt either.

  51. (NEW!) Repair Tungsten (1/3)
  52.  
  53. Today, it seems we have a surplus of Tungsten(VI) hexachloride left over from our other experiments. We'd like to recover the tungsten as well as produce some hydrochloric acid, so adding hydrogen should not only produce our desired results but release energy too.
  54.  
  55. Of course, this is SpaceChem so our molecules are going to need a little help to make this happen.

  66. Nonsense Organic (1.5/3)
  67.  
  68. A research level about producing some sort of organic molecule. Again, this level is generous and provides 8 bonders, but there aren't any other conveniences like sensors or quantum tunnels.
  69.  
  70. In fact, this level can also be solved without flip-flops. Fond memories of the main campaign, right?

  81. Uranium Oxide Reduction (1.5/3)
  82.  
  83. A research level about dealing with three different uranium oxide inputs, using only bonders
  84. and quantum tunnels. If you're familiar with sorting molecules using either input molecule shapes, or using bonders, grab/drops and such, then this exercise will be a piece of cake. If not, well, now's the time to learn.
  85.  
  86. Optimizing this one will probably come down to squeezing individual cycles/symbols out of the solution.

  97. (NEW!) A Small Push (1.5/3)
  98.  
  99. A relatively straightforward decomposition of a large organic molecule into two smaller copies (and some hydrogen). The procedure is pretty straightforward, so it's OK if you only have two bonders to do it with, right?
  100.

  110. (NEW!) Pushed Together (1.5/3)
  111.  
  112. The companion assignment to A Small Push. Now that we've created our small organic pieces of ethenone (ketene), we can dimerize them together into diketene. After that, in SpaceChem 2.0, there will be an assignment that has two diketene inputs and asks them to be combined into tetraacetic acid or something silly like that. But I'm getting ahead of myself.

  123. (NEW!) Easier Done Than Said (1.5/3)
  124.  
  125. Chlorodiphenylphosphine isn't hard to pronounce, and it isn't hard to combine two benzene rings and two phosphorous atoms into a large molecule. Right? After all, there's only twenty-six atoms here.
  126.

  137. (NEW!) Garlic Breath (1.5/3)
  138.  
  139. One of our research facilities is currently working with some odorless and highly toxic gases, so in the name of safety we have decided to add some allyl methyl sulfide into each of the pressurized tanks. The strong garlic odor should assist in early recognition of gas leaks and could potentially save precious cycles and/or lives.

  150. (NEW!) Cruel Benzene (1.5/3)
  151.  
  152. Today we need to synthesize some benzene rings. Unfortunately, we discovered a design flaw in our methylene supply reactors that allows some hydrogen gas to contaminate the supply. Worse, our on-site recycler is closed for maintenance. Our only option that fills our benzene ring quota on time is to work with our contaminated input using our nuclear reactor.
  153.  
  154. Don't worry about leaving garbage inside the reactor, either - we can clean it out later if necessary. It's more important that we get the rings finished before the deadline.

  196. (NEW!) Unnatural Gas (2/3)
  197.  
  198. Our client has requested we synthesize several liters of methyl azide, since they theorize it could be a less toxic alternative to sodium azide and lead azide. We can fill this order by combining various hydrocarbons with nitrogen gas, but we believe that our nuclear reactors may make this process more efficient than just throwing away excess hydrogen and carbon.

  210. (NEW!) Recycled Brick Acid (2/3)
  211.  
  212. As a proof of concept, we want to create common acids out of recycled bricks (from demolished buildings). These acids can then be used to clean the bricks of our old historic brick buildings that we actually want to preserve. The marketing department says they think they can sway some clients from SFCM to SpaceChem if we can put on a demonstration.
  213.  
  214. All our hydrogen reserves are currently occupied with other assignments, though, so you will need to create your hydrogen on-site.

  228.  
  229. It's time to perform chlorination and produce some 1,2 dichloroethane (not 1,1 dichloroethane!). Unfortunately, our reactor quota is pretty strict - 1 reactor. So the single reactor must both sort three different hydrocarbons and process all of them into 1,2 dichloroethane.

  241. Radioactive Salts (2.5/3)
  242.  
  243. Here's a fusion challenge where your job is to make three different salts. The reactor quota is strict, given how different each of the outputs' molecular masses are from one another. It shouldn't take too long to come up with a plan - again, the challenge here is going to be dealing with space constraints. As a side benefit, small loop optimizations will pay massive dividends (and ensure the salts get into the freighters before the actinides decay). Just kidding about that last part...
