Trade is difficulty with AI civs

Do not trade the tech on the interum turn, wait until you have control of the game and then do it. If you trade when someone calls you up, they will try to sell it to everyone.

It could be for a couple of reasons:
Firstly, the value of a tech drops according to how many civs know it (well, technically, the value to a particular civs drops with the number of civs that that civs knows that have it). Also, often techs appear "worthless" because the AI simply doesn't have enough money to buy them.

Yes you can see a loss in value as you traded and it is worth more to some than others as they could have more or less contacts with the knowledge. The other aspect is if civ A has been researching it, it has some investment and it is not going to be willing to pay full frieght.
This is why you can see them saying no way or some such, they are close to a break through and do not want to spend for it.
Often you can trade with the civ with the most cash first, but sometimes they are the ones that are close to getting it.

There are two very important rules in tech trading:
1) a monopoly tech costs twice as much to buy. Where "monopoly" is defined as "the buyer knows of only one civ that knows the tech".
2) as more civs (that the buyer has contact with) knows a tech, the price to buy or to research the tech goes down.
These rules apply to both the players and to the AI.
In your example, after you sold the tech to the first civ, the tech will de-value by more than 50% when you sell to the second one. That's 50% from losing its monopoly status (rule 1), plus a little more from having a second civ knowing that tech (rule 2).
First, [edit: as vmxa pointed out
x-post] B may be researching the tech. That will lower their purchase price by however many beakers that they have already invested into the tech. If you sell to B first, then you're selling it at monopoly price. The doubling in price more than covers any researched discount that B gets. But if you sell to A first, then by the time you get to B, you're selling it at normal 3rd civ price, and B doesn't have to pay full 3rd civ price buy the tech.
A second explaination is as ainwood said, the AI may not have enough money to pay for it. You trade adviser will tell you if this is the case. If 30gpt is "okay" and 31gpt is "close", then the AI still has more money. But if 31gpt is "impossible", then it means the AI has no more money to offer.
