Tue, 03 Aug 2004 Ignition! In between other serious shit (don't ask) I'm keeping my spirits up by reading a rare-as-hen's-teeth copy of Ignition! An informal history of liquid rocket propellants, by John D. Clark. It's a wonderful source of insights into how rocket scientists got their reputation: ... But then Pino, in 1949, made a discovery that can fairly be described as revolting. He discovered that Butyl Mercaptan was very rapidly hypergolic with mixed acid. This naturally delighted Standard of California, whose crudes contained large quantities of mercaptans and sulfides which had to be removed in order to make their gasoline socially acceptable. So they had drums and drums of mixed butyl mercaptans, and no use for it. If they could only sell it for rocket fuel life would indeed be beautiful. Well, it had two virtues, or maybe three. It was hypergolic with mixed acid, and it had a rather high density for a fuel. And it wasn't corrosive. But its performance was below that of a straight hydrocarbon, and its odor --! Well, its odor was something to consider. Intense, pervasive, and penetrating, and resembling the stink of an enraged skunk, but surpassing, by far, the best efforts of the most vigorous specimen of Mephitis mephitis. It also clings to the clothes and the skin. But rocketeers are a hardy breed, and the stuff was duly and successfully fired, although it is rumored that certain rocket mechanics were excluded from their car pools and had to run behind. Ten years after it was fired at the Naval Air Rocket Test Station -- NARTS -- the odor was still noticeable around the test areas. (And at NARTS, with more zeal than judgement, I actually developed an analysis for it!) California Research had an extremely posh laboratory at Richmond, on San Francisco Bay, and that was where Pino started his investigations. But when he started working on the mercaptans, he and his accomplices were exiled to a wooden shack out in the boondocks at least two hundred yards from the main building. Undeterred and unrepentant, he continued his noisome endeavors, but it is very much worth noting that their emphasis had changed. His next candidates wer enot petroleum by-products, nor were they chemicals which were commercially available. They were synthesized, by his own crew, specifically for fuels. Here at the very beginning of the 50's, the chemists started taking over from the engineers, synthesizing new propellants (which were frequently entirely new compounds) to order, instead of being content with items off the shelf. Anyhow, he came up with the ethyl mercaptal of acetaldehyde and the ethyl mercaptol of acetone, with the skeleton structures C | C--C--S--C--S--C--C and C--C--S--C--S--C--C | | C C respectively. The odor of these was not so much skunk-like as garlicky, the epitome and concentrate of all the back doors of all the bad Greek restaurants in all the world. And finally he surpassed himself with something that had a dimethylamino group attached to a mercaptan sulfur, and whose odor can't, with all the resources of the English language, even be described. It also drew flies. This was too much, even for Pino and his unregenerate crew, and they banished it to a hole in the ground another two hundred yards further out into the tule marshes. Some months later, in the dead of night, they surreptitiously consigned it to the bottom of San Francisco Bay. They don't make 'em like that any more.
